Java 删除文件
删除文件
要在 Java 中删除文件，请使用 delete() 方法:
实例
import java.io.File; // 导入 File 文件类
public class DeleteFile {
public static void main(String[] args) {
File myObj = new File("filename.txt");
if (myObj.delete()) {
System.out.println("Deleted the file: " + myObj.getName());
} else {
System.out.println("Failed to delete the file.");
}
}
}输出将是:
Deleted the file: filename.txt
删除文件夹

实例
import java.io.File;
public class DeleteFolder {
public static void main(String[] args) {
File myObj = new File("C:\\Users\\MyName\\Test");
if (myObj.delete()) {
System.out.println("Deleted the folder: " + myObj.getName());
} else {
System.out.println("Failed to delete the folder.");
}
}
}输出将是:
