input.java

用eclipse开发的java程序

package com.fugle.util;

import java.io.*;

public class Input
{

	/**
	 * @param args
	 */
	
	public static InputStreamReader in = new InputStreamReader(System.in);
	public static BufferedReader read = new BufferedReader(in);
	
	/*
	static
	{
	in = new InputStreamReader(System.in);
	read = new BufferedReader(in);
	}
	*/
	
	public static String getInput()
	{
		String s = " ";
		try
		{
			s = read.readLine();
			
		}
		catch(IOException e)
		{
			System.out.println("输入信息错误,请重新输入一个字符串!");
			
		}
		//if(s == null)
		//	return s = "unknown";
		//else
			return s;
	}
	
	public static int getInputIntValue()
	{
		//String s = getInput();
		int i = -1;
		while(i < 0)
		{
			String s = getInput();
			try
			{
				i = Integer.parseInt(s);
			
			}
			catch(Exception e)
			{
				//System.out.println("i=" + i);
				System.out.println("输入信息错误,请重新输入一个整数!");
			}
		}
		return i;
	}
	
	
	public static void main(String[] args)
	{
		// TODO Auto-generated method stub

		//System.out.println(Input.getInputIntValue());
		
	}
