public class ArrayDemo02 {
    
    
    public static void main(String[] args) {
    
    
        //静态初始化：创建+赋值
        int[] a = {
    
    1,2,3,4,5,6,7,8,9,10};
        System.out.println(a[2]);
        //动态初始化：包含默认值
        int[] b = new int[10];
        b[0] = 10;
        System.out.println(b[0]);
        System.out.println(b[3]);
    }
}
