2018/4/11[learned one-dimensional arrays and multidimensional arrays, but did the problem of choice.

The textbook is the Java language Program design of Tsinghua University Press

Today's lecture is about one-dimensional arrays and multidimensional arrays

A two-dimensional array is a combination of multiple one-dimensional arrays.

A multidimensional array is an accumulation of successive downward arrays.

Like what:

Three-dimensional =n two-dimensional =nxm one-dimensional

Although the study is fur, the exercise will work hard to do in the near future!
