java数组的声明基础

public class Demo01 {
        //用数组申明10个数，10个数的合输出
        public static void main(String[] args) {

            int[] sum = new int[10];//声明数组，创建数组
            //给数组赋值
            sum[0] = 1;
            sum[1] = 2;
            sum[2] = 3;
            sum[3] = 4;
            sum[4] = 5;
            sum[5] = 6;
            sum[6] = 7;
            sum[7] = 8;
            sum[8] = 9;
            sum[9] = 10;
            int s = 0;
            for (int i = 0; i<=sum.length;i++){
                s = s+i;
                System.out.println(s);

            }

//静态数组初始化
int[] i = {1,2,3,4,5,6};
System.out.println(i[5]);
//动态数组初始化
int[] s = new int[5];
s[0] = 1;
s[1] = 2;

s[3] = 4;
s[4] = 5;
System.out.println(s[2]);

        }
