如何使用 charAt() 和 br.skip() 克服 \n(Enter)？

Question

在这个给定的程序输出中显示空白，原因是 name.The 原因是我们使用了 read() 和 readLine() 方法。

//Employee details

import java.io.*;

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

        // create BufferedReader object to accept data from keyboard
        BufferedReader br = new BufferedReader(
                new InputStreamReader(System.in));

        // accept employee details
        System.out.print("Enter id:");
        int id = Integer.parseInt(br.readLine());

        System.out.print("Enter sex(M/F):");
        char sex = (char) br.read();

        System.out.print("Enter name:");
        String name = br.readLine();

        // display the employee details
        System.out.println("Id:" + id);
        System.out.println("Sex:" + sex);
        System.out.println("Name:" + name);
    }
}

输出：

输入id:10
输入性别(M/F):M
输入姓名：id:10
性别：M
姓名：

有两种方法可以解决这个问题：

br.readLine().charAt(0)
br.skip(2)

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

        // create BufferedReader object to accept data from keyboard
        BufferedReader br = new BufferedReader(
                new InputStreamReader(System.in));

        // accept employee details
        System.out.print("Enter id:");
        int id = Integer.parseInt(br.readLine());

        System.out.print("Enter sex(M/F):");
        char sex = (char) br.read();
        //Solution #1 : char sex = br.readLine().charAt(0)

        //Solution #2 : skip 2 characters if using (char) br.read()
        br.skip(2)

        System.out.print("Enter name:");
        String name = br.readLine();

        // display the employee details
        System.out.println("Id:" + id);
        System.out.println("Sex:" + sex);
        System.out.println("Name:" + name);
    }
}

输出：

Enter id:10
Enter sex(M/F):M
Enter name:Vinay
id:10
sex: M
Name:Vinay
