public class Basic15 {

public static void main(String[] args) {

Basic15 my = new Basic15();

my.go();

}

public void go()

{

System.out.println(“请输入3个整数”);

Scanner sc;

int a=0;

int b=0;

int c=0;

try {

sc = new Scanner(System.in);

a = sc.nextInt();

b = sc.nextInt();

c = sc.nextInt();

} catch (Exception e) {

// TODO Auto-generated catch block

System.out.println(“输入有误”);

go();

}

compare(a, b, c);
