readfile.java

我初学java时两个星期写的源代码

package com.softeem.jbs;

import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Properties;

/**
 * 先把.txt文件放入文件输入ir，然后把ir放入数据输入流dr，最后用properties存储dr，过后再关闭。

public class ReadFile {

	public static void main(String[] args) {
		Properties pt = new Properties();
		FileInputStream ir = null;
		try {
			ir = new FileInputStream("d:\\file.txt");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		DataInputStream dr = new DataInputStream(ir);
		try {
			pt.load(dr);
			dr.close();
			ir.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
		Enumeration en = pt.propertyNames();
		while (en.hasMoreElements()) {
			String s = (String) (en.nextElement());
			System.out.println(s + "=" + pt.getProperty(s));
		}

	}
