How tor write into Existing File

[agajantorayev]

Hello everybody, I have the txt file with data:
----------------------------------------------------------
Line number 0: This is the text test format for javaEdu folder
Line number 2:
Line number 3:
----------------------------------------------------------
Now I want to ADD the following: "Line number 4: testing Line 4"

I tried it like:

import java.io.*;
public class Buff3{
    public static void main(String [] args) throws Exception{
        String strFile="D:/javaEdu/test.txt";
        BufferedWriter bos=null;
        try{
            FileWriter fos=new FileWriter(strFile);
            bos =new BufferedWriter(fos);
            bos.write("Line 4: testing Line 4");
        }finally{
            if(bos!=null){
                bos.flush();
                bos.close();
            }
        }
    }
}

But this code does not add Line 4 but owerwrites test.txt. How can I add Line 4 into existing file without overwriting it???

FileWriter fos=new FileWriter(strFile);
Should be
FileWriter fos=new FileWriter(strFile, true);
