java写入txt文件

用另一个构造方法FileWriter fileWriter=new FileWriter("c:\\Result.txt", true); // true代表追加

同理
BufferedWriter writer = new BufferedWriter(new FileWriter(new File("c:\\Result.txt"), true));


就是如何不覆盖的写入一个txt文件，不要把原来的内容覆盖掉，要加个什么定位语句，最好在下面的基础上加上。

FileWriter fileWriter=new FileWriter("c:\\Result.txt");   
int [] a=new int[]{11112,222,333,444,555,666};   
for (int i = 0; i < a.length; i++) {    
fileWriter.write(String.valueOf(a[i])+" ");    
 }   
fileWriter.flush();   
fileWriter.close();

try{    
 BufferedWriter writer = new BufferedWriter(new FileWriter(new File("c:\\Result.txt")));     
writer.write("\"101\",\"英语\",\"english\",\"100001\"\r\n");          
writer.close();    
 }catch(Exception e){   
  }
