Which of the following is the correct way to declare a constant in Java?

Consider the code :

public class Test {

    public static void main(String[] args) {

        int[] a = {1, 2, 3};

        int[] b = a;

        b[0] = 99;

        System.out.println(a[0]);

    }

}

Given the following code :

class PolymorphismExample {

    void display(int a) {

        System.out.println("Method with int parameter: " + a);

    }

    void display(String a) {

        System.out.println("Method with String parameter: " + a);

    }

    public static void main(String[] args) {

        PolymorphismExample obj = new PolymorphismExample();

        obj.display("10 is an integer");

    }

}

What is the output of the following code?

To call the constructor Person( String firstName, String lastName) of a class "Person" from another constructor Person(String firstName) of the same class, we use the instruction this.Person(firstName, "Not defined")

The Open/Closed Principle states that a class should be:

The Dependency Inversion Principle recommends that:

What will be printed?

public class Test {

    public static void main(String[] args) {

        String s1 = "Java";

        String s2 = new String("Java");

        System.out.println(s1 == s2);

        System.out.println(s1.equals(s2));

    }

}
