        n= input.nextInt();

        for (int i=2; i<=n; i++){
            r= n%i;
            if (r==0){
                System.out.print("The number is composite");
                goto a: //want to jump from this loop to the a: label.

            }

            System.out.print("The number is prime");

        }
        a: //want to jump here if the if condition gets true... 

    }
}

Java中没有goto语句。只保留一个字。
