JAVA使用hasNext循环输入

hasNex循环输入的简单用法

import java.util.Random;
import java.util.Scanner;

public class Aaa {

public static void main(String[] args){
	Scanner scan = new Scanner(System.in);
	int a=0,b=0;
	while(scan.hasNext())
	{
		a=scan.nextInt();
		b=scan.nextInt();
		System.out.println(a);
		System.out.println(b);
	}
}

}
