   The main difference between <xref ref="java-array" text="type-global"/> and <xref ref="java-histogram" text="type-global"/> is that we declare <c>count</c> to be an <c>Array</c> of integers. We also can initialize short arrays directly using the syntax shown here: <c>Integer[] count = {0,0,0,0,0,0,0,0,0,0}</c>Then notice that we can use the square bracket notation <c>count[idx]</c> to index into an array.
