Question

Java: Code a class encapsulating a stack of clothes using an array. A clothing item has the following attributes: names, color, and whether it can be washed at high temperature. Limit your stack to 20 clothing items. In addition to creating your push, pop, and peek methods; create two additional methods: a method that return all of the clothing items of a given color; a method that returns how many clothing items in the stack can be washed at high temperature. Write a program to test your stack with all these methods.
