Check if file exists

With this example we are going to demonstrate how to check if a File exists. We are using the File class that is an abstract representation of file and directory pathnames. In short, to check if a File exists you should:

  • Create a new File instance by converting the given pathname string into an abstract pathname.
  • Use exists() API method of File. This method tests whether the file or directory denoted by this abstract pathname exists. It returns true if and only if the file or directory denoted by this abstract pathname exists and false otherwise.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

import java.io.File;

public class CheckIfFileExists {
	
	public static void main(String[] args) {
		
		File file = new File("C://file.txt");
		
		// Tests whether the file denoted by this abstract pathname exists.
		boolean exists = file.exists();
		 
		System.out.println("File " + file.getPath() + " exists: " + exists);
		
	}

}

 
This was an example of how to check if a File exists in Java.
