My question is how to write the code in WareHouse.java

This is WareHouse.java

package warehouse;

/*

*

* This class implements a warehouse on a Hash Table like structure,

* where each entry of the table stores a priority queue.

* Due to your limited space, you are unable to simply rehash to get more space.

* However, you can use your priority queue structure to delete less popular items

* and keep the space constant.
