在 Java 中删除目录
方法java.io。可用于删除具有所需抽象路径名的目录。此方法不需要参数，成功删除目录时返回true，否则返回false。File.delete()
演示这一点的程序如下-
示例
import java.io.File;
public class Demo {
public static void main(String[] args) {
boolean flag;
String directory = "D:\\a";
File file = new File(directory);
flag = file.mkdir();
System.out.println("The directory is created? " + flag);
flag = file.delete();
System.out.println("The directory is deleted? " + flag);
}
}上述程序的输出如下-
输出结果
The directory is created? true The directory is deleted? true
现在让我们了解上面的程序。
使用java.io方法创建并删除该目录。.然后打印此方法返回的布尔值。演示这一点的代码片段如下-File.delete()
boolean flag;
String directory = "D:\\a";
File file = new File(directory);
flag = file.mkdir();
System.out.println("The directory is created? " + flag);
flag = file.delete();
System.out.println("The directory is deleted? " + flag);
