How to statically initialize an array using Java?

Concept

1. Refers to executing the content in the static initialization block. When creating an array, directly determine the elements.

2. Format

数据类型[] 数组名 = new 数据类型[]{元素1,元素2,...};

Example

package com.itheima.array2;
 
public class Demo1Array {
    /*
        数组静态初始化 : 初始化时指定每个数组元素的初始值，由系统决定数组长度
 
        完整格式:
                    数据类型[] 数组名 = new 数据类型[]{数据1,数据2,数据3...};
        简化格式:
                    数据类型[] 数组名 = {数据1,数据2,数据3...};
     */
    public static void main(String[] args) {
        // 数据类型[] 数组名 = new 数据类型[]{数据1,数据2,数据3...};
        int[] arr = new int[]{11,22,33};
        System.out.println(arr[0]);
        System.out.println(arr[1]);
        System.out.println(arr[2]);
 
        // 数据类型[] 数组名 = {数据1,数据2,数据3...};
        int[] arr2 = {44,55,66};
        System.out.println(arr2);
        System.out.println(arr2[0]);
        System.out.println(arr2[1]);
        System.out.println(arr2[2]);
 
    }
}
