如何使用Java代码删除日志文件的内容

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;


// code

public static void clearFile(String fileLocation){
    try{
        BufferedWriter bw = new BufferedWriter(new FileWriter(fileLocation));
        bw.write("");
        bw.flush();
        bw.close();
    }catch(IOException ioe){
        // You should really do something more appropriate here
        ioe.printStackTrace();
    }
}</pre></code>
