public class referencemystery3 {
public static void main(string[] args) {
int a = 7;
int b = 9;
point p1 = new point(2, 2);
point p2 = new point(2, 2);
addtoxtwice(a, p1);
system. out. println(a + " " + b + " " + p1.x + " " + p2.x);
addtoxtwice(b, p2);
system. out. println(a + " " + b + " " + p1.x + " " + p2.x);
}

public static void addtoxtwice(int a, point p1) {
a = a + a;
p1.x = a;
system. out. println(a + " " + p1.x);
}
}
