Uncover the Secrets of File Names in Java

The Power of the getName() Method

One of the most straightforward ways to get a file name is by using the getName() method of the File class. This method returns the name of the file, stripping away the directory path.

File file = new File("C:\\Users\\username\\Documents\\example.txt");
String fileName = file.getName();
System.out.println(fileName); // Output: example.txt

String Manipulation: A Different Approach

But what if we want to get creative and use string methods to extract the file name? We can do just that! By converting the File object to a string and using the lastIndexOf() and substring() methods, we can achieve the same result.

File file = new File("C:\\Users\\username\\Documents\\example.txt");
String stringFile = file.toString();
int index = stringFile.lastIndexOf('\\');
String fileName = stringFile.substring(index + 1);
System.out.println(fileName); // Output: example.txt

Mastering File Names in Java

As you can see, getting a file name from an absolute path in Java is a breeze. Whether you choose to use the getName() method or string manipulation, the result is the same – a neat and tidy file name.

• Use the getName() method for a straightforward approach.
• Employ string manipulation techniques for a more creative solution.

So, go ahead and practice these techniques to become a master of file names in Java!
