java如何接收键盘输入信息？java中从键盘接受字符串的函数咋写

在public static void main(String [] args){

}里

添加如下代码 .Scanner input=new java.util：java.util亲，你好

Scanner san = new Scanner(System.in);

String 输入的信息 = san.nextInt();

java的键盘监听事件

Scanner sc = new Scanner(System.in);//定义监听

String strNum = sc.next();//获取字符串值

Scanner san = new Scanner(System.in);

String 输入的信息 = san.nextInt();

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class Print {

public static void main(String[] args) throws Exception{

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

System.out.println(br.readLine());

br.close();

}

}

util.Scanner;

class StrBuffer

{

public StrBuffer()

{

}

public static void main(String[] args)

{

System.out.println(请输入":".println("用这个更好

import java.out;

Scanner scanner = new Scanner(System.in);

String str = scanner.next();

System;); + str);输出字符串
