In this article, we discussed how to remove the extension from a given file name.įirst, we discussed different options for deleting extensions. To use the utility method, we need to add the Guava library to our classpath. For example, if we use Maven as the build tool, we can add Guava dependencies to our pom.xml files: guava 30.0-jre įirst, let's take a look at the implementation of this method: public static String getNameWithoutExtension(String file) Six, conclusion Starting from version 14.0, Guava introduced (()) methods. It allows us to easily remove the extension from a given file name. In addition, we will also discuss a general method to solve the problem of removing the extension from a given file name. In this tutorial, we will test whether the utility methods provided by Guava and Apache Commons IO can handle all the situations listed above. ': If we only want to delete one extension, the result should be '.nf'. Otherwise, if we delete all extensions, then '. baeldung ': Since this file name does not have any extension, the file name should not be changed either. Therefore, we expect in the results.

baeldung.tar However, if we want to delete all extensions from the file name, ' baeldung ' is the correct result ' ': This file name contains two extensions. If we only want to delete one extension, it should be.

' baeldung.txt ': This is a simple example. The correct result is ' baeldung ' ' baeldung ': The file name has no extension. Therefore, instead of changing the file name, you should get ' baeldung ' Next, after removing the extension, we will list the expected results of the above example: Point files have multiple extensions, such as '. baeldung 'ĭotfile with a single extension, such as '. Has multiple extensions, such as ' 'ĭotfile without extension, such as '. Without any extension, such as ' baeldung”įor a single extension, this is the most common case, such as ' baeldung.txt ' However, if we study this issue carefully, it may be more complicated than we thought.įirst, let's look at the types of file names that can be: When we first looked at it, we might think that removing the extension from the file name is a very easy problem. 2.The scheme of removing the extension from the file name In this tutorial, we will discuss general methods for removing extensions from file names. When we use Java to process files, we often need to process file names. For example, sometimes we want to get the name without extension from a given file name. In other words, we want to delete the file name extension.
