java输入之Scanner用法简介说明

scanner对象创建

定义scanner类的方法
    Scanner scan = new Scanner(System.in)

读取整数:
    int x = scan.nextInt();

    nextxx：读取空格隔开的数据

package com.java265;

import java.util.Scanner;

class Test{
	public static void main(String[] arg){
		Scanner sc = new Scanner(System.in);
		String str = sc.nextLine().toString();
		String[] arr  = str.split("\\s+");
		int[] b = new int[arr.length];
		for(int j = 0; j<b.length;j++) {
			b[j] = Integer.parseInt(arr[j]);
			System.out.println(b[j]+" "); 
		}
		
	}
	
}
