• how use labels in java code? 2 answers

i can see below code compiles in java not understand reason?

public class test {       @suppresswarnings("unused")     public static void main(string[] args) {          abc:system.out.println(9);     } } 

the line in main labelled statement.

these labels aren't use in isolation, can used break , continue statements.
