What this statement do "system.exit(x)"?

Question

I saw a question in which first a value is assigned to X and then come this statement "system.exit(x)"
System.out.println(X)

Answer 1

System.exit() method exits current program by terminating running Java virtual machine. This method takes a status code.
Here X is a status code.
If X = 0 means it will terminate successfully.
if X = 1 or -1 or any other non-zero value– Generally indicates unsuccessful termination
