文件创建读取（自用勿点）

小时候控制台游戏所用的工具类，有毒哈哈哈哈：

1、txt传记记录文件：

import java.io.File;
import java.io.FileNotFoundException;

			String expath= path.replace(".", "_re.");

			System.out.println(expath);

             while ((line = br.readLine()) != null) {
                 out.println(line);      
             }
             if (br != null) {

             }
		} catch (FileNotFoundException e) {

		} catch (IOException e) {

		}
	}
	
	/**

2、存档对象记录工具类：

package com.yy.diabio.v1.utils;

     }
     
     //再读取对象

      	if(!file.exists()){
      		try {

      	}
    	 
         FileInputStream fis=null;

     }*/
}

3、properties记录类：

package com.yy.diabio.v1.utils;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.Map;

public class propertiesBath {
	//初始化properties

	public static void main(String[] args) {
		Properties pro = new Properties();
		try {
		    InputStream inStr = ClassLoader.getSystemResourceAsStream("Role.properties");
		    pro.load(inStr);
		} catch (FileNotFoundException e) {
		    e.printStackTrace();
		} catch (IOException e) {
		    e.printStackTrace();
		}


		//返回所有的属性名，即键名。
		//propertyNames(),返回属性列表中所有键的枚举
		Enumeration enu2=pro.propertyNames();
		while(enu2.hasMoreElements()){
		    String key = (String)enu2.nextElement();
		    System.out.println(key);
		} 


		//返回所有的属性值。
		//Properties 继承于 Hashtable，elements()是Hashtable的方法，返回哈希表中的值的枚举。
		Enumeration enu=pro.elements();
		while(enu.hasMoreElements()){
		    String key = (String)enu.nextElement();
		    System.out.println(key);

		} 


		//返回所有的属性（属性名，属性值）。
		//Properties 继承于 Hashtable，entrySet()是Hashtable的方法，
		//返回此 Hashtable 中所包含的键的 Set 视图。此 collection 中每个元素都是一个 Map.Entry
		Iterator it=pro.entrySet().iterator();
		while(it.hasNext()){
		    Map.Entry entry=(Map.Entry)it.next();
		    Object key = entry.getKey();
		    Object value = entry.getValue();
		    System.out.println(key +":"+value);
		}
	}
}
