要在Java中拷贝整个目录并改名,你可以使用递归的方式来实现。下面是一个示例代码,演示了如何拷贝整个目录并将其重命名:
```java
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.StandardCopyOption;
public class DirectoryCopyExample {
public static void main(String[] args) {
String sourcePath = "/path/to/source/directory";
String destinationPath = "/path/to/destination/directory";
String newDirectoryName = "new_directory_name";
try {
copyDirectory(new File(sourcePath), new File(destinationPath, newDirectoryName));
System.out.println("Directory copied successfully.");
} catch (IOException e) {
System.out.println("Failed to copy directory: " + e.getMessage());
}
}
private static void copyDirectory(File source, File destination) throws IOException {
if (!source.isDirectory()) {
throw new IllegalArgumentException("Source is not a directory.");
}
if (!destination.exists()) {
destination.mkdirs();
}
File[] files = source.listFiles();
if (files != null) {
for (File file : files) {
Path sourcePath = file.toPath();
Path destinationPath = new File(destination, file.getName()).toPath();
Files.copy(sourcePath, destinationPath, StandardCopyOption.REPLACE_EXISTING);
if (file.isDirectory()) {
copyDirectory(file, new File(destination, file.getName()));
}
}
}
}
}
```
请替换 `sourcePath` 和 `destinationPath` 变量的值为你实际的源目录和目标目录路径,以及 `newDirectoryName` 为你想要的新目录名称。运行代码后,源目录将被拷贝到目标目录,并且以新的目录名称命名。
