This example demonstrates how we can use the FileUtils class listFiles() method to search for a file specified by their extensions. We can also define to find the file recursively deep down into the subdirectories. package org.kodejava.commons.io; import org.apache.commons.io.FileUtils; import java.io.File; import java.util.Collection; public class SearchFileRecursive { public static void main(String[] args) { File root […]
