Return_type In Java [closed]

static int comparess(int x)
{

  if(x==100)
    return x;
  else 
    return 200;
}
public static void main(String args[]){
    int a=25;     //or just anything
    int result;
    result=comparess(a);
}

I am sorry to be asking a silly question
but i am just a beginner
Can anyone explain me why this gives an error

method must return a int type

like i am still returning an int type even when the else part is executed
