Java_Properties类实现软件使用次数

import java.io.*;import java.util.*;public class PropertiesText1 {public static void main(String[] args) throws IOException {Properties pro = new Properties();File f = new File("G:\\ABC");f.mkdirs();File file = new File(f,"count.ini");if(!file.exists())file.createNewFile();//FileReader fis = new FileReader(file);FileInputStream fis = new FileInputStream(file);pro.load(fis);int count = 0;String value = pro.getProperty("time");if(value!=null){count = Integer.parseInt(value);if(count>=5){System.out.println("使用次数已到，请注册！！");return;}}count++;pro.setProperty("time",count+"");//FileWriter fos = new FileWriter(file);FileOutputStream fos = new FileOutputStream(file);pro.store(fos,"ABC");fos.close();fis.close();}}
