Write a Java Program to Delete Empty and Non-empty Directory
PROGRAM: Java Program to Delete Empty and Non-empty Directory
/*Java Program to Delete Empty and Non-empty Directory*/
1: Java Program to delete an empty directory
import java.io.File;
class Main {
public static void main(String[] args) {
try {
// create a new file object
File directory = new File(“Directory”);
// delete the directory
boolean result = directory.delete();
if(result) {
System.out.println(“Directory Deleted”);
}
else {
System.out.println(“Directory not Found”);
}
} catch (Exception e) {
e.getStackTrace();
}
}
}
2: Delete a non-empty directory
import java.io.File;
class Main {
public static void main(String[] args) {
try {
// create a new file object
File directory = new File(“Directory”);
// list all the files in an array
File[] files = directory.listFiles();
// delete each file from the directory
for(File file : files) {
System.out.println(file + ” deleted.”);
file.delete();
}
// delete the directory
if(directory.delete()) {
System.out.println(“Directory Deleted”);
}
else {
System.out.println(“Directory not Found”);
}
} catch (Exception e) {
e.getStackTrace();
}
}
}
3: Delete non-empty directory recursively
import java.io.File;
class Main {
public static void deleteDirectory(File directory) {
// if the file is directory or not
if(directory.isDirectory()) {
File[] files = directory.listFiles();
// if the directory contains any file
if(files != null) {
for(File file : files) {
// recursive call if the subdirectory is non-empty
deleteDirectory(file);
}
}
}
if(directory.delete()) {
System.out.println(directory + ” is deleted”);
}
else {
System.out.println(“Directory not deleted”);
}
}
public static void main(String[] args) {
try {
// create a new file object
File directory = new File(“Directory”);
Main.deleteDirectory(directory);
} catch (Exception e) {
e.getStackTrace();
}
}
}
