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 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);
}
} |
Hash Code: 1600751599
Program 2:
// 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);
}
} |
Hash Code: -996777206
