One-dimensional array instead of two-dimensional array
Because of the very good performance of random access to arrays, many JDK libraries, such as ArrayList, Vector, and so on, use arrays as their array implementations. However, as a software developer, you must also know that the access speed of one-bit array and two-dimensional array is not the same. The access speed of one-digit array is better than that of two-dimensional array. Therefore, if you want to use a two-dimensional array in a performance-sensitive system, you can try to change the two-dimensional array into an one-dimensional array through a reliable algorithm, so as to improve the response speed of the system.
