public String getName()

Parameters

NA

Return Value

This method returns name of the file or directory or empty string if pathname's name sequence in empty.

Exception

NA

Example 1

The following example shows the usage of Java File getName() method. We've created two File references. Then we're creating a File Object using test.txt which is not present in the current directory. Then we've created the file using createNewFile() method. Now using getAbsoluteFile() method, we're getting the file and getting the name of file using getName() method and then we're checking if file exists using exists() method.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      File f1 = null;
      String path = "";
      boolean bool = false;
      
      try {
         // create new files
         f = new File("test.txt");
         
         // create new file in the system
         f.createNewFile();
         
         // create new file object from the absolute path
         f1 = f.getAbsoluteFile();
         
         // returns true if the file exists
         bool = f1.exists();
         
         // returns name of file
         path = f1.getName();
         
         // if file exists
         if(bool) {
         
            // prints the file
            System.out.print(path+" Exists? "+ bool);
         }
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

test.txt Exists? true

Example 2

The following example shows the usage of Java File getName() method. We've created a File reference. Then we're creating a File Object using F:/test.txt which is present in the provided directory. Now using getAbsoluteFile() method, we're getting the file and printing its name after getting the name of file using getName() method.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      
      try {
         // create new files
         f = new File("F:/test.txt");         
    
         // get the file
         File f1 = f.getAbsoluteFile();
         
         // prints the file name
         System.out.println("File: "+f1.getName());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

File: test.txt

Example 3

The following example shows the usage of Java File getName() method. We've created a File reference. Then we're creating a File Object using F:/test directory which is present in the provided location. Now using getAbsoluteFile() method, we're getting the directory and its name using getName() method.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      
      try {
         // create new files
         f = new File("F:/test");         
    
         // get the file
         File f1 = f.getAbsoluteFile();
         
         // prints the file name
         System.out.println("Directory: "+f1.getName());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Directory: test
