关于DataInputStream和DataOutputStream的求助

import java.io.DataInputStream;  
import java.io.DataOutputStream;  
import java.io.EOFException;  
import java.io.FileInputStream;

public class DataStreamDemo {

        //write data to file  
        DataOutputStream out = null; 
        DataInputStream in = null;  
        int count = 10;

            } catch (IOException e) {}  
        }

}  

这样一段文件输入输出的代码，如果我想每次写入的随机数都写在原来的随机数后面而不是覆盖掉原来的随机数 应该怎么修改呢？？？？请教了。
[最优解释]
out = new DataOutputStream(
new FileOutputStream("e:\\data.txt",true));
