The following example shows the usage of java.io.File.hashCode() method.

package com.tutorialspoint;

import java.io.File;

public class FileDemo {
   public static void main(String[] args) {
      
      File f = null;
      int v;
      boolean bool = false;
      
      try{
         // create new file
         f = new File("C:\\test.txt");
         
         // returns hash code for this abstract pathname
         v = f.hashCode();
         
         // true if the file path exists
         bool = f.exists();
         
         // if file exists
         if(bool)
         {
            // prints
            System.out.print("The hash code for this abstract pathname: "+v);
         }
      }catch(Exception e){
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result:

The hash code for this abstract pathname: -246273912
