Texture problem

hi 

i have a  problem, i've made an entity and it works fine.

the problem is  i need to give it more than one texture, like the horse has 4-5 ish diffrent textures.

public class EntityButtMob extends EntityAnimal{

private int r;

public ResourceLocation texture1, texture2, texture3, texture4, texture5, texture6, texture7, texture8, texture9;

public static ResourceLocation TE;

public EntityButtMob(World par1World) {

super(par1World);

this.setSize(0.5F, 0.4F);

this.tasks.addTask(0, new EntityAIWander(this, 0.5D));

this.tasks.addTask(1, new EntityAIPanic(this, 1.0D));

this.tasks.addTask(2, new EntityAITempt(this, 0.7D, Items.beef, false));

this.tasks.addTask(4, new EntityAIFollowParent(this, 1.1D));

this.tasks.addTask(2, new EntityAIMate(this, 1.0D));

Random rand = new Random();

r = rand.nextInt(;

switch®{

case 1:

TE = texture1;

break;

case 2:

TE = texture2;

break;

case 3:

TE = texture3;

break;

case 4:

TE = texture4;

break;

case 5:

TE = texture5;

break;

case 6:

TE = texture6;

break;

case 7:

TE = texture7;

break;

case 8:

TE = texture8;

break;

default:

TE = texture9;

}

}

super.applyEntityAttributes();

this.getEntityAttribute(SharedMonsterAttributes.maxHealth).setBaseValue(16.0F);

}
