+### for 循环作业
+
+1. 让用户输入一个数字,根据这个数字,循环输出"我爱学习,我爱java",比如,用户输入数字 9 就在控制台输出9行"我爱学习,我爱java"
+
+```
+import java.util.Scanner;
+
+public class zy03 {
+    public static void main(String[] args) {
+        Scanner a= new Scanner(System.in);
+        System.out.println("请输入");
+        int  a1 = a.nextInt();
+        for (int a2=1; a2<=a1;a2++){
+            System.out.println("我爱学习,我爱java");
+        }
+    }
+}
+```
+
+2.用户分别输入数 a,数b,让程序实现从a 开始循环到b.输出"有生之年,能看到中国队出线吗?"
+
+```
+import java.util.Scanner;
+
+public class zy03 {
+    public static void main(String[] args) {
+        Scanner n1= new Scanner(System.in);
+        System.out.println("请输入A");
+        int  a1 = n1.nextInt();
+        Scanner n2= new Scanner(System.in);
+        System.out.println("请输入B");
+        int  a2 = n2.nextInt();
+        for (int i=a1; i<=a2;i++){
+            System.out.println("有生之年,能看到中国队出线吗?");
+        }
+    }
