java:I/O 往原文件追加内容

原来txt内容:

"我要添加内容"

import java.io.*;

class Test {
    public static void main(String[] args) {
        FileWriter fw = null;
        BufferedWriter bw = null;
        String con = "tinyphp";
        try {
            fw = new FileWriter("e://d/add.txt", true);      //加true
            bw = new BufferedWriter(fw);
            bw.write(con);
        } catch (Exception e) {
            System.out.println(e);
        } finally {
            try {
                bw.close();
                fw.close();
            } catch (Exception e) {
                System.out.println(e);
            }
        }
    }
}

运行后:文本为

"我要添加内容tinyphp"
