Java Merge Two Directories to One

This is a method I write for merging two directories. The directory of second parameter will be moved to the first one, including files and directories.

package com.programcreek;
 
import java.io.File;
 
public class MergeTwoDirectories {
	public static void main(String[] args){
		String sourceDir1Path = "/home/programcreek/Desktop/d1";
		String sourceDir2Path = "/home/programcreek/Desktop/d2";
 
		File dir1 = new File(sourceDir1Path);
		File dir2 = new File(sourceDir2Path);
 
		mergeTwoDirectories(dir1, dir2);
 
	}
 
	public static void mergeTwoDirectories(File dir1, File dir2){
		String targetDirPath = dir1.getAbsolutePath();
		File[] files = dir2.listFiles();
		for (File file : files) {
			file.renameTo(new File(targetDirPath+File.separator+file.getName()));
			System.out.println(file.getName() + " is moved!");
		}
	}
}

Output:

f1 is moved!
f2 is moved!
testdir is moved!
