How to write a method that translates a boolean value to yes or no,

Question

I am new to java and I need to write a method that translates a boolean value of true or false to the string "yes" or "no". I'm a little lost.

public class Book
{
    private String title;
    private String author;
    private String isbn;
    private int pages;
    private boolean pback;
    private double price;

    /**
     * Constructor for objects of class Book
     */
    public Book(String bookTitle, String bookAuthor, String bookCode, int bookPages, boolean paperback, double bookRetail)
    {
        // initialise instance variables
        title = bookTitle;
        author = bookAuthor;
        isbn = bookCode;
        pages = bookPages;
        pback = paperback;
        price = bookRetail;
    }


public String translate(boolean trueorFalse)
            {
                if(pback = true)
                    {
                        ??????;
                    }            
                 else(pback = false)
                    {
                        ???????;
                    } 

            }

Answer 1

boolean myBoolean = true;
String result = myBoolean ? "yes" : "no";

Answer 2

The operator is your friend:

public static String translate(boolean trueOrFalse) {
    return trueOrFalse ? "yes" : "no";
}

In general, if you find yourself writing:

SomeType x;
if (someCondition) {
    x = someExpression;
} else {
    x = someOtherExpression;
}

it is usually better to use:

SomeType x = someCondition ? someExpression : someOtherExpression;

The conditional statement ensures that only one of someExpressionor is evaluated someOtherExpression, so you can use method calls, etc., assured that they will not be executed improperly.

Apache Group, Apache Commons Lang Java, Boolean. BooleanUtils :

toStringOnOff(boolean bool) - converts a boolean to a String returning 'on' or 'off'
toStringOnOff(Boolean bool) - converts a Boolean to a String returning 'on', 'off' or null
toStringTrueFalse(boolean bool) - converts a boolean to a String returning 'true' or 'false'
toStringTrueFalse(Boolean bool) - converts a Boolean to a String returning 'true', 'false' or null
toStringYesNo(boolean bool) - converts a boolean to a String returning 'yes' or 'no'
toStringYesNo(Boolean bool) - converts a Boolean to a String returning 'yes', 'no' or null

toStringYesNo.

boolean myBoolean = false;
String result = BooleanUtils.toStringYesNo(myBoolean);
System.out.println(result);

no

"" "", :

        //say your boolean variable is called gotIt
            if(gotIt == true) //you can also just say if(gotIt) here
                {
                    //here you place the string where it needs to be, either output it or place it into a variable
                     System.out.println("Yes");
                }            
             else
                {
                    //same as above but for false
                    System.out.println("No");
                }

Answer 7

, :

public String translate(boolean trueOrFalse)
{
    return String.valueOf(trueOrFalse);
}

:

public boolean translateBack(String translation)
{
    return Boolean.parseBoolean(translation);
}

"true" "false":)

Answer 8

String yesNo(boolean b) {
    String[] s = {"yes", "no"};
    return b ? s[0] : s[1];
}
