Question

java在命令行中实现输入

比如在命令行运行后,提示输入一个值,中文英文都可以,然后根据所输入的东西,生成一个语句.
比如,输入;u
输出:u are a fool.
请在命令行下测试过再给我,因为我是菜鸟,错误的我不知道怎么改.

Answer 1

这样：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public static void main(String[] args) {
InputStreamReader isr = new InputStreamReader(System.in);

BufferedReader br = new BufferedReader(isr);
String s = null;
try {
s = br.readLine();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

System.out.println("Hello: " + s);

}

肯定是保无误才给你的呀！！试试看就知道了，

Answer 2

package com.color.util;

import java.util.Scanner;

public class InputStr{

public static void main(String[] args){
Scanner s = new Scanner(System.in);
String str = s.next();
System.out.println(str+" are a fool!");
}
}

Answer 3

int rs=System.in.read();
或者
int rs=System.in.read(byte[] b);
for(int i=0;i<b.length;i++){
System.out.println("b["+i+"]"+b[i]);//输出b
}

Answer 4

import java.io.*;
public class test{
public static void main(String args[]){
byte buffer=new byte[512];
System.in.read(buffer);
String str=new String(buffer);
System.out.println("请你输入:");
System.out.println("what you are input is"+str);
}
}
