How can I move files to another folder with java?
提问by Sebastian Tare B.
I want to move files (images) from a folder to another:
我想将文件（图像）从一个文件夹移动到另一个文件夹：
For example:
例如：
/home/folder1/image.png
/home/folder1/image.png
to
到
/home/folder1/folder2/image.png
/home/folder1/folder2/image.png
And obviously remove the image from the folder1
并且显然从folder1中删除图像
I've trying to do it by reading the path and then modifying it, or using renameTo, but i can't do it.
我试图通过读取路径然后修改它或使用 renameTo 来做到这一点，但我做不到。
I hope someone can help me a little with this, Thanks.

Well I can put the code but it's simple to explain what i did:
好吧，我可以放代码，但很容易解释我所做的：
I just created a Folder class that has a File object of my folder (/home/folder1) , i read all the images inside and save it in an File array, then i scan it and try to change the path of every image file String to another
我刚刚创建了一个 Folder 类，它具有我的文件夹 (/home/folder1) 的 File 对象，我读取里面的所有图像并将其保存在一个 File 数组中，然后我扫描它并尝试更改每个图像文件 String 的路径到另一个

Thanks to all for the help, all are good examples, I was able to change my files to another location, there was a bunch of files I wanted to move so, I didn't want to create too many objects.
感谢所有人的帮助，都是很好的例子，我能够将我的文件更改到另一个位置，我想移动一堆文件，所以我不想创建太多对象。

You said you tried renameTo and it didn't work, but this worked for me. After I renamed it I deleted the original file.
你说你试过 renameTo 但它没有用，但这对我有用。重命名后，我删除了原始文件。
File a = new File("C:\folderA\A.txt");
a.renameTo(new File("C:\folderB\" + a.getName()));
a.delete();

我没有运行这个，但它应该可以工作
File f1 = new File("/home/folder1/image.png");
File f2 = new File("/home/folder1/folder2/image.png");
f1.renameTo(f2);

There are many approaches for you to do that. This snippet is one of them, you can move your files like this way:
有很多方法可以让您做到这一点。这个片段就是其中之一，您可以像这样移动文件：
try {
final File myFile = new File("C:\folder1\myfile.txt");
if(myFile.renameTo(new File("C:\folder2\" + myFile.getName()))) {
System.out.println("File is moved successful!");
} else {
System.out.println("File is failed to move!");
}
}catch(Exception e){
e.printStackTrace();
}

In java 8+ you can simply use Files.movefrom nio:
在 java 8+ 中，您可以简单地使用nio 中的Files.move：
try {
Path source = Paths.get("/home/folder1/image.png");
Path dest = Paths.get("/home/folder1/folder2/image.png");
Files.move(source, dest);
} catch (IOException e) {
...
}
The paths can even come from different file system providers (ie a ZipFileSystem).
路径甚至可以来自不同的文件系统提供者（即 ZipFileSystem）。
