求助Scanner相关问题

Question

package flowControl;import java.util.Scanner;public class Ifequal {public static void main(String[]arg){ Scanner sc=new Scanner(System.in); System.out.println("请输入x的值"); int x=sc.nextInt(); System.out.println("请输入x的值"); int y=sc.nextInt(); sc.close(); if(x!=0){ if(x>y){ System.out.println(x+">"+y); } else{ System.out.println(x+"<"+y); } } else{ System.out.println(x+"="+y); }}}第一行的x可以扫描，第二行y无法扫描
