compare Attack and Defence attribute

Hi, A unit will have Defense rating per each of the 8 elements ( example shorten to 4 for simplicity).
And an attack will be one of the element.

public class DefenceAtt{
	
	public int PHY;
	public int ENERGY;
	public int HEAT;
	public int FROST;
	
	public DefenceAtt()
	{
		PHY 	= 0;
		ENERGY 	= 0;
		HEAT 	= 0;
		FROST 	= 0;
	}
}

public enum ELEMENT{ PHY, ENERGY, HEAT, FROST, LAST };

public class Attack{
     public int power;
     public ELEMENT element;

     public DealDamage(pow, element) { /*DO Something here*/ }
}

Beside using SWITCH statement, is there any other convenient way to compare the Attacking Element to the related defence attribute?

THX in advance,

Use Builtin arrays. Instead of using four variable with each name, use public int[] defenceAtt = new int[4]; and create a enum/constant like

public enum ELEMENT()
{
   PHY   = 0;
   ENERGY    = 1;
   HEAT  = 2;
   FROST     = 3;
}

so

public DealDamage(pow, element) {
    defenceAtt[element]-=pow;
}
