Explanation:

• Create the method to accept an Array object of type String representing colors with a return type of an ArrayList
• Within the method body, create and initialize an Arraylist
• Use a for loop to iterate the Array of cloths.
• Use an if statement within the for loop to check if item equals blue and add to the Arraylist.
• Finally return the arrayList to the caller
