please someone explain why this program gives a compile error.
class Example{
public static void main(String args[]){
final int x;
x=101;
int y;
if(x>100){
y=-1;
}
System.out.println(y);
}
}

Reshadee, welcome to the Ranch!

Please post the compiler error text. Does the error message have anything to do with the final variable x?

Oh and before you post any more code, you might like to learn how to UseCodeTags <- link


luck, db

Why is that code so similar to the code in this thread and this one?
Please always tell us where code comes from.

And likely, this one too. There seems to be a large group asking the same similar questions, at the same time -- probably caused by the people taking the same class.

So, this is a reminder to all ranchers, please SearchFirst. Your question may already been answered.
