Here I draw some diagrams to show how arrays look like in memory and in cache. This is not a programming problem, but let’s assume we use C not Java. The following diagram shows how a 8*8 array/matrix stored in memory by using row-major. If CPU need A[0][7] element, the whol...

Also, if you’re using an IDE, you don’t need to do all of this manually. For example: in Eclipse, you can generate a toString method by opening the Book.java and right-click on the source code and select: Source > Generate > toString ...
Since a Java array has a range of [0, array length - 1], when an attempt is made to access an index outside this range, anArrayIndexOutOfBoundsExceptionis thrown. Besides arrays, this exception can also happen with strings, ArrayLists, and any other data structure that uses indexing to...
