one of my friend ask this question to me please give me the answer of this question and explanation
thax
// When matchXY method will retrurn true?

public class Test{
  private static int x,y;
  private void setX(int x){
this.x = x;
  }
  private void setY(int y){
this.y = y;
  }
  public void setXY(int a){
    setX(a);
    setY(a);
  }
  public boolean matchXY(){
    return x==y;
  }
public static void main(String args[]){
    System.out.println( new Test().matchXY() );    
  }
}

I don't see any relevance of this question to threads..... are the methods supposed to be synchronized?
as it stands, the program returns true when run, without calling setXY(). the static variables x and y are set to their default values of 0.
since you are only calling matchXY(), then both x and y are equal so it returns true!
am I missing something here

Shoba,
i totally agree with Amir. you might want to go through the code again and check if you have missed something....as your question pertaining to threads , seems no relevance here with this particular code snippet...therefore it comes across as a question , about static variables being initialised to 0 , hence being equal , when the method matchXY() is called , which in turn returns true !!!
