The hashCode() method of UUID class in Java is generally used to get the hash code value of the UUID.
Syntax:
Java
Java
public int hashCode()Parameters: This method does not take any parameter. Return Value: This method returns an integer value which is the hashCode value for this UUID instance. Below programs illustrate the working of hashCode() method: Program 1:
// Java code to illustrate hashCode() method
import java.util.*;
public class UUID_Demo {
public static void main(String[] args)
{
// Creating two UUIDs
UUID UUID_1
= UUID
.fromString(
"58e0a7d7-eebc-11d8-9669-0800200c9a66");
// Displaying the UUID
System.out.println("UUID: "
+ UUID_1);
// Displaying the hashCode value
System.out.println("The hashCode value is: "
+ UUID_1.hashCode());
}
}
Output:
Program 2:
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The hashCode value is: 3744873
// Java code to illustrate hashCode() method
import java.util.*;
public class UUID_Demo {
public static void main(String[] args)
{
// Creating two UUIDs
UUID UUID_1
= UUID
.fromString(
"5fc03087-d265-11e7-b8c6-83e29cd24f4c");
// Displaying the UUID
System.out.println("UUID: "
+ UUID_1);
// Displaying the hashCode Value
System.out.println("The hashCode value is: "
+ UUID_1.hashCode());
}
}
Output:
UUID: 5fc03087-d265-11e7-b8c6-83e29cd24f4c The hashCode value is: -1447957042
