java请任意输入内容，用空行结束程序

public static void main(String args[])

{

Scanner scanner = new Scanner(System.in)

do

{

System.out.println("请任意输手败饥入内容，用空行结束枯哗程序")

String line = scanner.nextLine()

String space = "毕返 "

if (line.endsWith(space))

return

} while (true)

}

键盘输入肆巧李宽链若干行,输入空格按回合结束

BufferedReader reader = new BufferedReader(new InputStreamReader(

System.in))

System.out.println("输入空格结束按回车结束"裂迟)

StringBuffer inputStr = new StringBuffer()

System.out.print("请输入: ")

do {

String line = reader.readLine()

System.out.println(line)

if (line.equals(" ")) {

break

}

inputStr.append(line+"\n")

} while (true)

System.out.println(inputStr.toString())

}

java结束Scanner类输入的大概思路就是读取一行数据，以换行结束，示例如下：

import java.io.BufferedReader

import java.io.IOException

import java.io.InputStreamReader

import java.util.Scanner

public class test{

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

// 创建输入流对象

       BufferedReader reader = new BufferedReader(new InputStreamReader(System.in))

       // 读取一行信息前败

     敏空  String input = reader.readLine()

       // 以空格为分隔符，转换成数组

       String[] numbers = input.split(" ") 

       for(int j=0j<numbers.lengthj++)

      慧拿颤 {

        System.out.print(Integer.parseInt(numbers[j]))

       }

      

  } 

}
