Answer 1

a)

public class MyClass {

    public static void main(String args[]) {

        int num1=3;

        int num2=4;

        int num3=5;

       

        String first="moon";

        String second="sun";

        String third="moon";

       

        while(((num1==num3||num2==num3)&&first.equals(second)||first.equals(third))||(first.equals(third)&&num3==num1))

        {

        System.out.println("Hello" );

        break;

    }

    }

}

Output

Hello

Explanation

Here the while statement below evaluates as follows . Here F indicates False and T indicates True.

(((num1==num3||num2==num3)&&first.equals(second)||first.equals(third))||(first.equals(third)&&num3==num1))

=(((F||F)&&F||T)||(T&&F))

=((F&&F||T)||(T&&F)

=((F||T)||(T&&F))

=(T||F)

=True

Here while evaluates to true and hello in the loop is printed.

b)

public class MyClass {

    public static void main(String args[]) {

        int num1=3;

        int num2=4;

        int num3=5;

       

        String first="dog";

        String second="sun";

        String third="moon";

       

        while(((num1==num3||num2==num3)&&first.equals(second)||first.equals(third))||(first.equals(third)&&num3==num1))

        {

        System.out.println("Hello" );

        break;

    }

    }

}

Output

Explanation

Here the while statement below evaluates as follows . Here F indicates False and T indicates True.

(((num1==num3||num2==num3)&&first.equals(second)||first.equals(third))||(first.equals(third)&&num3==num1))

=(((F||F)&&F||F)||(F&&F))

=((F&&F||F)||(F&&F)

=((F||F)||(F&&F))

=(F||F)

=False

Here while evaluates to false and nothing is printed as output.

c)

public class MyClass {

    public static void main(String args[]) {

        int num1=3;

        int num2=3;

        int num3=3;

       

        String first="cat";

        String second="cat";

        String third="moon";

       

        while(((num1==num3||num2==num3)&&first.equals(second)||first.equals(third))||(first.equals(third)&&num3==num1))

        {

        System.out.println("Hello" );

        break;

    }

    }

}

Output

Hello

Explanation

Here the while statement below evaluates as follows . Here F indicates False and T indicates True.

(((num1==num3||num2==num3)&&first.equals(second)||first.equals(third))||(first.equals(third)&&num3==num1))

=(((T||T)&&T||F)||(F&&T))

=((T&&T||F)||(F&&T)

=((T||F)||(F&&T))

=(T||F)

=True

Here while evaluates to true and hello in the loop is printed.
