Level hashCode() method in Java with Examples
  • Last Updated : 14 Oct, 2019

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:
Program 1:






// 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);
    }
}
Output:
HashCode = 800

Program 2:




// Java program to illustrate hashCode() method
  
import java.util.logging.Level;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Get level of logger
        Level level
            = Level.parse("SEVERE");
  
        // get hash Code
        int value = level.hashCode();
  
        // print result
        System.out.println("Hash Code = "
                           + value);
    }
}
Output:
Hash Code = 1000
