Given the fоllоwing clаss аnd cоde: public clаss Point {private int x;private int y; public Point(int x, int y) { this.x = x; this.y = y;} public void move(int dx, int dy) { x += dx; y += dy;} public String toString() { return "(" + x + ", " + y + ")";}}public static void main(String[] args) {Point p1 = new Point(1, 2);Point p2 = p1;p2.move(3, 4);System.out.println(p1);System.out.println(p2);} a) What two lines are printed? b) Briefly (1–2 sentences) describe the memory situation with p1 and p2 after main runs (aliasing).Aliasing means any change through p1 will also affect what you see through p2
