Path hashCode() method in Java with Examples

The Java Path interface was added to Java NIO in Java 7. hashCode() method of java.nio.file.Path used to return a hash code for this path after computing hashcode. The hashcode is always the same if the object doesn’t change. Hashcode is a unique code generated by the JVM at time of object creation. It can be used to perform some operation on hashing related algorithm like a hashtable, hashmap etc. An object can also be searched with its unique code (hashcode).

Syntax:

int hashCode()

Parameters: This method accepts nothing.

Return value: This method returns the hash-code value for this path.

Below programs illustrate hashCode() method:

import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
    public static void main(String[] args)
        throws IOException
    {
  
        // create object of Path
        Path path
            = Paths.get("D:/workspace/AmanCV.docx");
  
        // call hashCode() to get hashCode
        int hashCode = path.hashCode();
  
        // print hashCode
        System.out.println("Hash Code: "
                           + hashCode);
    }
}
