Java Multidimensional Arrays Guide

In Java, multiple dimensions of changes can be implemented using arrays, collections, enums, and other methods. Below are explanations of several common ways to achieve this.

1. One way to represent multiple dimensions of change is by using arrays. For example, you can use a two-dimensional array to represent changes on a 2D plane. Here is an example code:

int[][] matrix = new int[3][3];
matrix[0][0] = 1;
matrix[0][1] = 2;
matrix[0][2] = 3;
// 其他操作

1. To represent a two-dimensional list, below is an example code:

List<List<Integer>> matrix = new ArrayList<>();
matrix.add(Arrays.asList(1, 2, 3));
matrix.add(Arrays.asList(4, 5, 6));
// 其他操作

1. Using enumerations: Enumerations can be used to represent multiple dimensions of change. For example, an enumeration can be used to represent the multiple states of a state machine. The following is an example code:

enum State {
    STATE_1,
    STATE_2,
    STATE_3
}

State currentState = State.STATE_1;
// 切换状态
currentState = State.STATE_2;

By using the above method, it is possible to achieve multidimensional changes and select the appropriate way to represent and handle multidimensional data based on actual needs.
