filemanager.java

本程序采用Java技术实现

package base.io;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.List;

public class FileManager  //文件写操作，存取用户帐号
{
	public static final String LAST_CHAR="\n";
	//写文件 参数(绝对路径,内容,是否创建,是否追加)
	public static void write(String path, String content,boolean isCreate,boolean isAppend) {
		try {
			//判断路径是否存在
			File file=new File(getShortPath(path));
			if(!file.exists()){
				if(isCreate)
					file.mkdir();
				else
					throw new java.io.FileNotFoundException(path);
			}
			//开始写文件
			FileWriter fw = new FileWriter(path);
			BufferedWriter bw = new BufferedWriter(fw);
			String array[] = content.split(LAST_CHAR);
			for (int i = 0; i < array.length; i++) {
				bw.write(array[i]);
				bw.newLine();
			}
			bw.flush();
			bw.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
//	写文件 参数(绝对路径,内容(集合),是否创建,是否追加)
	public static void write(String path, List list,boolean isCreate,boolean isAppend) {
		StringBuffer buffer=new StringBuffer();
		for(Object obj:list){
			buffer.append(obj+"\n");
		}
		write(path,buffer.toString(),isCreate,isAppend);
	}
	//获取不带文件名的路径
	public static String getShortPath(String path){
		return path.substring(0,path.lastIndexOf("\\")+1);
	}
