Java中获得键盘输入值的方法

1.接受键盘输入的字符

导入

         import java.io.*;

输入

         System.out.print("Enter a Char:");          char i = (char) System.in.read();          System.out.println(i);

2.控制台接受字符串

导入

         import java.io.*;

输入

         public static void main(String [] args) throws IOException         {            BufferedReader b = new BufferedReader(new InputStreamReader(System.in));            String str = null;            System.out.println("Enter your value:");            str = b.readLine();            System.out.println(str);           }

3.scanner类

导入

         import java.util.Scanner;

输入

         Scanner sc = new Scanner(System.in);          System.out.println("请输入你的姓名：");          String name = sc.nextLine();          System.out.println("姓名："+name);
