get the output of the following application

Answer 1

ANSWER

YOUR CODE PRODUCES ERROR AS A OUTPUT BECAUSE CODE CAN HAVE ONLY ONE PUBLIC CLASS. AND IT IS HAVING MORE THAN ONE PUBLIC CLASS OUTSIDE A SINGLE CLASS. SO RESULTS INTO ERROR.

OUTPUT

####################################################

HOWEVER AFTER REMOVING public KEYWORD FROM CLASS A AND B, YOU WILL GET OUTPUT.

MODIFIED CODE ALONG WITH OUTPUT IS SHOWN BELOW.

CODE

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

        A objA = new A();

        B objB = new B();

        System.out.println("in main(): ");

        System.out.println("objA.a = "+objA.getA());

        System.out.println("objB.b = "+objB.getB());

        objA.setA (222);

        objB.setB (333.33);

      System.out.println("objA.a = "+objA.getA());

        System.out.println("objB.b = "+objB.getB());

    }
    
}
    
    
class A {

    int a = 100;

    public A() {

        System.out.println("in the constructor of class A: ");

        System.out.println("a = "+a);

        a = 333;

        System.out.println("a = "+a);

    }

    public void setA( int value) {

        a = value;

    }

    public int getA() {

        return a;

    }

} //class A
class B {

    double b = 123.45;

    public B() {

        System.out.println("-----in the constructor of class B: ");

        System.out.println("b = "+b);

        b = 3.14159;

        System.out.println("b = "+b);

    }

    public void setB( double value) {

       b = value;

    }

    public double getB() {

        return b;

    }

} //class B
