Path hashCode() method in Java with Examples

Last Updated : 16 Jul, 2019

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: Program 1:

Java

// Java program to demonstrate
// java.nio.file.Path.hashCode() method

import java.io.IOException;
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);
    }
}

Output:

Hash Code: 1600751599

Program 2:

Java

// Java program to demonstrate
// java.nio.file.Path.hashCode() method

import java.io.IOException;
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:/Resume.pdf");

        // call hashCode() to get hashCode
        int hashCode = path.hashCode();

        // print hashCode
        System.out.println("Hash Code: "
                           + hashCode);
    }
}

Output:

Hash Code: -996777206
