LocalTime hashCode() method in Java with Examples

The hashCode() method of a LocalTime class is used to return hashCode for this time. 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 hashtable, hashmap etc. An object can also be searched with its unique code (hashcode).

Syntax:

public int hashCode()

Parameters: This method does not accept any parameter.

Return value: This method returns an integer value which is the hashCode.

Below programs illustrate the hashCode() method:

    {
        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("10:44:59.73");
  
        // get nano second field using getNano()
        int hashcode = time.hashCode();
  
        // print result
        System.out.println("hashCode: "
                           + hashcode);
    }
