+## 笔记
+
+1.一次性声明大量的用于存储数据的变量
+
+2.要存储的数据通常都是同类型数据，例如：考试成绩
+
+3.int[] scores = {100,100,100,100,100,100,100…}
+
+## 作业
+
+``` java
+public class D1 {
+    public static void main(String[] args) {
+        int[] arr =  new int[5];
+        Scanner sc = new Scanner(System.in);
+        System.out.println("请输入五个数");
+        arr[0]= sc.nextInt();
+        arr[1]= sc.nextInt();
+        arr[2]= sc.nextInt();
+        arr[3]= sc.nextInt();
+        arr[4]= sc.nextInt();
+        System.out.println(arr[0]);
+        System.out.println(arr[1]);
+        System.out.println(arr[2]);
+        System.out.println(arr[3]);
+        System.out.println(arr[4]);
+    }
+}
