Im totally lost on what to do for this (enqueue) contructoin method and need some examples to push me in the right direction.

Question

public void enqueue(E target) {
/** TODO if queue is full, expand capacity the array-based data collection,
* for example, doubling its size and copying the original data items into the new expanded array.
* Then insert a new data item with reference to the input target into the queue
* Do not forget to change the size
**/
}

Answer 1

I guess the tags are misleading.
Correct me if I am wrong but you are looking for a "Java code example on doubling array size for a queue if it's full."

I say Java because void return type syntax is not supported in JavaScript and NetBeans is a popular IDE for Java development for Desktop applications.

If yes then using tags like 'java' , 'queue' & 'array' can help Java programmers see your problem easily.

Answer 2

I wish I could help, did you find a solution?
