代码演示

package array;

import com.sun.xml.internal.ws.api.model.wsdl.WSDLOutput;

public class Demo01 {
    public static void main(String[] args) {
        int[] number;  //声明数组
        //   int nums2[];   //知道就行

        number = new int[10];   //创建数组

        //给数组元素赋值
        number[0] = 1;
        number[1] = 2;
        number[2] = 3;
        number[3] = 4;
        number[4] = 5;
        number[5] = 6;
        number[6] = 7;
        number[7] = 8;
        number[8] = 9;
        number[9] = 10;

        System.out.println((number[9]));  //正常取出
        
        System.out.println("---------------");
        
        System.out.println((number[10]));  //不存在数组下标为10的，越界异常
    }
