Is java pass by value or pass by reference

Is java pass by value or pass by reference ???

This is a confusing question, but I found a link that neatly explains things.

Try this:)

Java is pass by value for Primitives but it is pass by reference for objects.

Here is the proof: -

public class PassTest {

    public static void main (String args []) {

        int x = 10;

        System.out.println(passByValue(x));

        System.out.println(x);

        Point p = new Point (10, 10);

        passByReference(p);

        System.out.println(p.getX() + " -- "+ p.getY());

    }

   

    public static class Point {

        private int x;

        private int y;

       

        public Point (int a, int b) {

            x= a;

            y =b;

        }

       

        public int getX() {

            return x;

        }

        public void setX(int x) {

            this.x = x;

        }

        public int getY() {

            return y;

        }

        public void setY(int y) {

            this.y = y;

        }

    }

   

    public static int passByValue (int x) {

        return x + 10;

    }

   

    public static Point passByReference (Point p) {

        p.setX(p.getX() + 10);

        return p;

    }

}

Here us the output

20

10

20 -- 10
