Understanding how large or small certain items are essential when reading engineering drawings. While most engineering drawings are created in scale versions of 1/4-1/8 inches (.55-.275 centimeters) per foot, other scales may be used for very large creations. Always determine the scale of the drawing before examining it in detail. If the scale is not obviously evident on the drawing, consult with the engineer who drew it for clarification.
In computer science, a sparse array is an array in which most of the elements have the default value (usually 0 or null). The occurrence of zero-value elements in a large array is inefficient for both computation and storage. An array in which there is a large number of zero elements is referred to as being sparse.
Arrays in Java store one of two things: either primitive values (int, char, ...) or references (a.k.a pointers). When an object is creating by using new, memory is allocated on the heap and a reference is returned. This is also true for arrays, since arrays are objects.1.
