java - 谁能告诉我 read() 和 readline(); 之间有什么区别？

Question

package com.learn.java;

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

public class BufferReaderInput {

    public static void main(String[] args) throws IOException {
        BufferedReader bufferreaderIn = new BufferedReader(
                new InputStreamReader(System.in));
        System.out.println("Enter your Name");
        String Name = bufferreaderIn.readLine();

        System.out.println("Enter your age");
        int age = Integer.parseInt(bufferreaderIn.readLine());

        System.out.println("Enter your salary");
        int sal = bufferreaderIn.read();

        System.out.println("Hi, I'm " + Name + " my age is " + age
                + " and my salary is " + sal);
    }

}

当我使用 obj.read(); 输入薪水时，它没有给出正确的输出。

谁能告诉我 read() 和 readline() 有什么区别？

Answer 1

来自 documentation BufferedReader，我们为 read 准备了这个:

Reads a single character.

这是 readLine :

Reads a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed.

因此，区分一行何时被视为终止的细节，不同之处在于第一个读取单个字符，而第二个读取整行。
