class msgClass{
public int content;
}
public class FinalT5A{
private int sum = 2;
private int y = 1;
public int x = 1;
public void methodA(){
int x=0, y =0, i = 0;
while (i < 2){
msgClass myMsg = new msgClass();
myMsg.content = this.x;
this.y = this.y + methodB(myMsg, myMsg.content);
System.out.println(x + + y+ + sum);
y = this.y / 2;
x = y + sum/2 i;
sum = x + y + myMsg.content;
