    Smile Java Beginner. Help needed.

    Determine if a String is even or odd. An even number has a remainder of zero when being divided by two. An odd number is any number that does not have a remainder of zero when being divided by two.

    I would really appreciate if someone can help me with this Lab05c



    import static java.lang.System.*;
    import java.util.Scanner;

    public class Lab05c
    {
    public static void main ( String[] args )
    {










    }
    }


    ----------------------------------------------------------------------------------------------------

    import static java.lang.System.*;
    import java.util.Scanner;

    public class StringOddOrEven
    {
    private String word;

    public StringOddOrEven()
    {

    }

    public StringOddOrEven(String s)
    {

    word = s;
    }

    public void setString(String s)
    {
    word = s;

    }

    public boolean isEven()
    {









    return false;
    }

    public String toString()
    {
    String output="";





    return output;
    }
    }




    Sample Data :
    cat
    boot
    it
    a
    eleven
    thirteen
    odd
    even



    Sample Output :
    Enter a word :: cat
    cat is odd.

    Enter a word :: boot
    boot is even.

    Enter a word :: it
    it is even.

    Enter a word :: a
    a is odd.

    Enter a word :: eleven
    eleven is even.

    Enter a word :: thirteen
    thirteen is even.

    Enter a word :: odd
    odd is odd.

    Enter a word :: even
    even is even.

    Yes, I think I can understand what you're getting at.

    I think you want the

    length() method of the String class as you're trying to figure if the string length is even or odd, am I right?


    Also, you should consider using the modulus ( % ) operator. It is like the division (/) except that it returns the int remainder of the division.

    For instance 5%2 = 1

    I think you can do it now.
