How to initialize a two-dimensional array in Java

Course Introduction：1. Two-dimensional array description: An array is a container used to store data. Now the types stored in the array are no longer int, double.., but the stored array. The elements in the array are still arrays. We call it an array within an array, which is also a two-dimensional array. One more layer of dimensionality. Simply put, a two-dimensional array is an array whose elements are one-dimensional arrays. 2. Initialization method (1) Use braces to assign values directly, suitable for situations where the array elements have been determined (2) Given the size of the two-dimensional array (3) The length of the second dimension of the array can be changed, but has not changed 3.
