what code can do for this

You are to design a class called World.

The class has one attribute its name and an association relation with the class Entity. A World may contain up to $10$ Entities

The World class will require the following methods:

Get the number of Entities

getNumEntities$()$:int

Get all the entities

getEntities$()$ : Entity$[]$

Add an entity to the world

addEntity $($Entity e$)$: void

Delete the entity in a position from the array and return it

deleteEntity$($int pos$)$: Entity

Find an entity in the array by the name and return each position on the array

findEntity$($String name$)$: int

Move the coordinates of all the entities the positions given by the parameters

moveEntities $($int xVal, int yVal$)$: void

Display all the entities in the world

displayEntities$()$ : void

Draw a UML class diagram for the Entity and World classes showing their attributes, relations and methods.

Part $2$ World Implementation

Implement the class World using the UML diagram. You have to make sure that a World can contain up to $10$ entities and that all the methods are implemented. You must use an array and a counter as seen in the lecture. We will work with ArrayLists after the consolidation week.

When implementing the methods you can assume the following for each method:

AddEntity: The world has not reached the maximum capacity

DeleteEntity: There is an entity in that position

FindEntity: If the entity with that name is not found $-1$ is returned

$**$ Note$**$ You need to keep the name of the methods and their input and output parameters as specified in the design phase.
