Level hashCode() method in Java with Examples

The hashCode() method of java.util.logging.Level is used to get hashcode of the level object. The hashcode is always the same if the object doesn’t change. Hashcode is a unique code generated by the JVM at the time of object creation. We can use hashcode to perform some operation on hashing related algorithms like a hashtable, hashmap, etc. We can search for an object with that unique code.

Syntax:

public int hashCode()

Parameters: This method accepts nothing.



Return: This method returns an integer value which represents hashCode value for this level.

Below programs illustrate hashCode() method:

// Java program to illustrate hashCode() method
  
import java.util.logging.Level;
import java.util.logging.Logger;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Create a Logger
        Logger logger
            = Logger.getLogger(
                        Object.class.getName())
                  .getParent();
  
        // Get level of logger
        Level level
            = logger.getLevel();
  
        // get hashCode
        int val = level.hashCode();
  
        // print result
        System.out.println("HashCode = "
                           + val);
    }
}
