我正在尝试用
Java创建一个目录.如果它存在,我想删除该目录及其内容并创建一个新目录.我试图执行以下操作,但不删除该目录.新文件将附加到目录中.
File file = new File("path");
boolean isDirectoryCreated = file.mkdir();
if (isDirectoryCreated) {
System.out.println("successfully made");
} else {
file.delete();
file.mkdir();
System.out.println("deleted and made");
}
解决方法
public static boolean deleteDir(File dir) {
if (dir.isDirectory()) {
String[] children = dir.list();
for (int i=0; i<children.length; i++) {
boolean success = deleteDir(new File(dir,children[i]));
if (!success) {
return false;
}
}
}
return dir.delete();
}
