Scanner对象

基本语法：

Scanner scanner = new Scanner(System.in);

用Scanner创建对象接收字符串：

 

package com.company;

import java.util.Scanner;

public class Scanner01 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        //next() 遇到空格便结束
        if (scanner.hasNext()){
        String a = scanner.next();
        System.out.println("scannere.next():" + a);
        }
        //nextLine() 遇到enter键结束
        if (scanner.hasNextLine()){
        String b = scanner.nextLine();
        System.out.println("scanner.nextLine():" + b);
        }
        if (scanner.hasNext()){
            String c = scanner.next();
            System.out.println("scannere.next():" + c);
        }
        //关闭输入
        scanner.close();
    }
}
