public void EnQueue(T obj) { /********** Begin *********/ /********** End *********/ }

As an AI language model, I don't know the context of this method. However, based on the method name "EnQueue" and the parameter "obj", I assume this method is used to add an object to a queue data structure.

To implement this method, you can follow these steps:

1. Check if the queue is full. If it is, throw an exception or return an error message.

2. If the queue is not full, add the object to the back of the queue.

3. Update the rear pointer of the queue to point to the new last element.

Here is the code for the EnQueue method:

public void EnQueue(T obj) {
    if (IsFull()) {
        throw new Exception("Queue is full.");
    }
    queue[rear] = obj;
    rear = (rear + 1) % capacity;
}

Assuming that the queue is implemented as an array called "queue", the capacity of the queue is stored in a variable called "capacity", and the rear pointer of the queue is stored in a variable called "rear". The IsFull() method checks if the queue is full. If it is, the EnQueue method throws an exception. Otherwise, it adds the object to the back of the queue and updates the rear pointer accordingly. Note that the "%" operator is used to handle the case when the rear pointer reaches the end of the array and needs to wrap around to the beginning.
