new FileWriter(file);

new FileWriter(file,true);

package com.andy.file;

        if(!file.exists()){ 
            file.createNewFile(); 
        } 
        //使用true，即进行append file 
        FileWriter fileWritter = new FileWriter(file.getName(),true);
        BufferedWriter bufferWritter = new BufferedWriter(fileWritter); 
        bufferWritter.write(content);
