NOTE: Answers to self-check problems are posted publicly on our web site and are accessible to students. This means that self-check problems generally should not be assigned as graded homework, because the students can easily find solutions for all of them.
If you want to assign BJP end-of-chapter problems as homework, please consider using our Exercises or Programming Projects, the solutions to which are not publicly posted but are available to instructors only by request. Version of ComputePay program that uses variables to avoid redundant expressions:. The black rectangle is being drawn second, so it's covering up the white inner circle. The following code fixes the problem:. The problem is that the parameters for the drawRect and drawLine methods have different meanings.
In drawRectthe parameters are x, y, width, height ; in drawLinethey are x1, y1, x2, y2. To fix the problem, the third and fourth parameters passed to drawRect should be changed to 40 and 20 so that the rectangle's bottom-left corner will be at 50, The Draw7 program draws a series of progressively smaller black circles, each with its right and bottom edges touching the right and bottom corners of the window. Its output looks like this:. Code to read an integer from the user, then print even if that number is an even number or odd otherwise:.
The code incorrectly prints that even numbers not divisible by 3 are odd. The following change corrects the problem. Note the braces around the outer if statement:. The code won't ever print "Mine, too! It should use the equals method to compare them: if name.
Refactored code to reduce redundancy:. If the user could type any number, the code might need additional if statements to increment the proper count variable. If the user could type anything, even a non-integer, the code might need to use the hasNextInt method of the Scanner to ensure valid input before proceeding.
The problem with the given sumTo method is that the sum variable needs to be declared outside the for loop. The countFactors method shown will not compile. It should count the factors using a a cumulative sum; it should not return inside the loop when it finds each factor. Instead, it should declare a counter outside the loop that is incremented as each factor is seen. Code to produce a cumulative product by multiplying together many numbers that are read from the console:.
The expression equals 6. A fix would be to test that the value is close to 9. The toLowerCase method cannot be called on a char value, which is what the charAt method returns.
A better solution would be to call the Character. Code to examine a string and determine how many of its letters come from the second half of the alphabet 'n' or later :. The preconditions of printTriangleType method are that the three side lengths constitute a valid triangle. The preconditions of the getGrade method are that the grade parameter's value is between 0 and The medianOf3 code fails when n3 is the smallest of the three numbers; for example, when the parameters' values are 4, 7, 2the code should return 4 but instead returns 2.
The method could be correctly written as:. The following version of the code checks for these cases and throws exceptions:. The code fails when more than one number is odd, because it uses else if rather building java programs 4th edition pdf download if.
The tests should not be nested because they are not mutually exclusive; more than one number could be odd. The printLetters code has a fencepost problem; it will print a dash after the last letter.
The following code corrects the problem:. Sentinel loop that repeatedly prompts the user to enter a number and, once the number -1 is typed, displays the maximum and minimum numbers that the user entered:.
In this isPrime code the boolean flag isn't being used properly, because if the code finds a factor of the number, prime will be set to falsebut on the next pass through the loop, if the next number isn't a factor, prime will be reset to true again.
In this contains code the boolean flag isn't being used properly, because if the code finds the character, found will be set to truebut on the next pass through the loop, building java programs 4th edition pdf download, if the next character isn't chthen found will be reset to false again. The Zune code will get stuck in an infinite loop when the current date is the end of a leap year.
So the loop does not subtract any days and never terminates. It can be building java programs 4th edition pdf download by adding a break statement to the loop:. If the user types a token of the wrong type, the line of input should be consumed and the user should be reprompted. The following code implements the corrected behavior:. Code that prompts the user for a number and then prints a different message depending on whether the number was an integer or a real number:. Write code that prompts for three integers, averages them, building java programs 4th edition pdf download, and prints the average; robust against invalid input:.
A file is a named collection of information stored on a computer. We can read a file with a Scanner using the following syntax:. The Scanner should read a new File with the name test. The correct line of code is:.
There are 17 tokens in the input. The "string" tokens can be read with the next method. The "integer" tokens can be read with nextInt. The "real number" tokens can be read with nextDouble. The tokens are:. The correct string is:. Code that prompts the user for a file name and prints the contents of that file to the console as output:.
A PrintStream object is used to write to an external file. It has methods such as println and print. Code that repeatedly prompts the user for a file name until the user types the name of a file that exists on the system. After the code is executed, the numbers array contains the following element values:. After the code is executed, the data array contains the following element values:. The code to print the arrays and to compare them doesn't work properly.
An array traversal is a sequential processing of each of an array's elements. Problems that can be solved in this manner include printing an array, comparing two arrays for equality, and searching an array for a given value. Code that uses a for loop to print each element of an array named data :. After the code is executed, the list array contains the following element values:.
To building java programs 4th edition pdf download the count and equals methods process arrays of String s, you must change int[] to String[] and replace all other occurrences of the word int with String.
The method to swap array elements works because, unlike integers, building java programs 4th edition pdf download, arrays are objects and use reference semantics. This means that changes to an array parameter's elements will be seen in the original array by the caller. After the mystery method is executed, the arrays contain the following element values:. After the mystery2 method is executed, the arrays contain the following element values:.
After the mystery3 method is executed, the array contains the following element values:. Code that constructs a two-dimensional array of integers with 5 rows and 10 columns, filled with a multiplication table:. After the mystery2d method is executed, the numbers array contains the following element values:.
Procedural programming treats a program as a sequence of actions or commands to perform. Object-oriented programming looks at a program as a group of interacting entities named objects that each keep track of related data and behavior.
An object is an entity that encapsulates data and behavior that operates on the data. A class is the blueprint for a type of object, specifying what data and behavior the object will have and how to construct it. The state of a String object is its sequence of characters which are actually stored internally as an array of char values. A String object's behavior includes its methods, such as lengthsubstringtoUpperCaseand indexOf. The state of a Calculator object might include the number that has just been computed, as well as another number that is currently being input.
A more complex Calculator object might also include a memory feature that stores an additional value. The behavior of a Calculator building java programs 4th edition pdf download might include methods to add, subtract, multiply, building java programs 4th edition pdf download, divide, and perhaps carryout other math operations such as exponentiation, logarithms, and trigonometric functions like sine and cosine.
A field is a variable that exists inside of an object. A parameter is a variable inside a method whose value is passed in from outside. Fields have different syntax because they are usually declared with the private keyword and not in a method's header. A field's scope is throughout the class, while a parameter's scope is limited to the method.
An accessor provides the client access to some data in the object, while a mutator lets the client change building java programs 4th edition pdf download object's state in some way. Accessors' names often begin with "get" or "is", while mutators' names often begin with "set". Correct syntax for calling computeInterest method on a BankAccount object:.
A constructor is a special method that creates an object and initializes its state. It's the method that is called when you use the new keyword. A constructor is declared without a return type. The keyword this refers to the object on which a method or constructor has been called sometimes called the "implicit parameter".
It is used to access or set the object's field values, to call the object's methods, or to call one constructor building java programs 4th edition pdf download another.
