+## JAVA 基础语法
+
+键盘录入
+
+1、导包。Scanner 类在java.util包下,所以需要将该类导入。导包的语句需要定义在类的上面。
+
+```java
+import java.util.Scanner;
+```
+
+2、创建Scanner对象。
+
+```java
+Scanner sc = new Scanner(System.in);// 创建Scanner对象,sc表示变量名,其他均不可变
+```
+
+3、接收数据
+
+```java
+int i = sc.nextInt(); // 表示将键盘录入的值作为int数返
+```
+
+实例
+
+```java
+import java.util.Scanner;
+public class ScannerDemo {
+ public static void main(String[] args) {
+ //创建对象
+ Scanner sc = new Scanner(System.in);
+ //接收数据
+ int a = sc.nextInt();
+ //输出数据
+ System.out.println(a);
+ }
+}
+```
+
+类型大小
+
+等级顺序:byte,short,char --> int --> long --> float --> double
+
+**注意:**
+
+1. /和%的区别:两者都做除法,
+ - / 取结果的商,
+
+ - % 取结果的余数。
