Java - File getName() Method
Description
The Java File getName() method returns the last name of the pathname's name sequence, that means the name of the file or directory denoted by this abstract path name is returned.
Declaration
Following is the declaration for java.io.File.getName() method −
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
