把字符串写入文本文件，在结尾追加内容

先把字符串写入文件，在结尾追加内容，利用的是printWriter.println(String s);

package com.file;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;

public class FileTest {

	public static void main(String []args){
		File file = new File("f:/file.txt");
		String s = "这是刚开始的文本";
		FileWriter fileWriter = null;
		PrintWriter printWriter = null;
		try {
			 fileWriter = new FileWriter(file);
			 fileWriter.write(s);
			 fileWriter.close();
		} catch (IOException e) {
			e.printStackTrace();
		}finally{
			if(fileWriter!=null){
				try {
					fileWriter.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
		
		try{
			String str = "\r\n这是追加的文本";
			fileWriter = new FileWriter(file,true);
			printWriter = new PrintWriter(fileWriter);
			printWriter.println(str);
			printWriter.close();
			fileWriter.close();
		}catch(Exception e){
			e.printStackTrace();
		}finally{
			if(printWriter!=null){
				printWriter.close();
			}
			if(fileWriter!=null){
				try {
					fileWriter.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}
}
