java中写到文件东西，怎么已追加的形式存到文本文件中去啊？
下面是代码， FileWriter FileWriter pw = new FileWriter(
"e:\\aa.txt ");
pw.write(allnumber[f1] + " "
+ allnumber[s2] + " "
+ allnumber[t3] + " "
+ allnumber[f4] + " "
+ allnumber[f5] + " "
+ allnumber[s6] + " ");
pw.close();
在aa。txt文件中，我要出现很多组数据，但是最终，他只显示了一组，应该是在写入的时候都覆盖了前面写入的数据，现在，怎么改下代码，可以让它一追加的形式添加的aa.txt文件中去，那个追加的方法早忘记了，请各位帮下忙.
------解决方案--------------------
FileWriter pw = new FileWriter( "e:\\aa.txt ",true);
------解决方案--------------------
java.io.FileWriter fw = new java.io.FileWriter( "e:\\aa.txt ",true);
看一下API文档嘛...
FileWriter(文件路径,是否追加);
------解决方案--------------------
