You can check if the abstract pathname of a File object exists using the exists() method.
import java.io.File; public class Main { public static void main(String[] args) throws Exception { // Create a File object File myFile = new File("dummy.txt"); // Check for the file's existence boolean fileExists = myFile.exists(); if (fileExists) { System.out.println("The dummy.txt file exists."); } else {/*ww w .j a va 2s . c o m*/ System.out.println("The dummy.txt file does not exist."); } } }
