public static void main(String[] args) throws IOException {
InputStreamReader reader = new InputStreamReader(System.in);
BufferedReader input = new BufferedReader(reader);
System.out.print("Enter your name: ");
String name = input.readLine();
System.out.println("Hello, " + name + "!");

Posted by: yeehya Posted on: 2003-12-24 15:38 我想继续问一下: 如果我想输入的字符是int 型的. 也就是说我想read 出来的还是int 型,我应该怎么办> 我记得BufferedReader 类.没有readInt的方法吧! 是不是可以用别的类实现输入! 还是需要再调用一个stringToInt的方法呀! 请执教, 先谢谢!

import java.io.*;

public class YearOfBirth {
public static void main(String[] args) throws IOException {
InputStreamReader reader = new InputStreamReader(System.in);
BufferedReader input = new BufferedReader(reader);
System.out.print("Enter your age: ");
String text = input.readLine();
int age = new Integer(text).intValue();
System.out.println("You are " + age + " years old, now,");
int year = 2003 - age;
System.out.println("so you were probably born in " + year);
}
}
