+3. 定义一函数，用于求2个数中的较大数，并将其返回，这2个数字在主函数中由用户输入
+
+   ```java
+   import java.util.Scanner;
+   
+   public class jhg {
+       public static void main(String[] args) {
+           Scanner scanner = new Scanner(System.in);
+           System.out.println("请输入a的值");
+           int a = scanner.nextInt();
+           System.out.println("请输入b的值");
+           int b = scanner.nextInt();
+      int s = getNum(a,b);
+           System.out.println("最大值为："+s);
+       }
+   
+       private static int getNum(int a,int b) {
+           int max = a>b?a:b;
+           return max;
+       }

+4. 在主函数中从键盘接收X, Y , Z3个数，编写函数计算这3个数的立方和并返回计算结果：S=X3+Y3+Z3

+```java
+import java.util.Scanner;
+
+public class jhg {
+    private static int X = 0;
+    private static int Z = 0;
+    private static int S = 0;

+    public static void main(String[] args) {

+         X = scanner.nextInt();
+        System.out.println("请输入Y的值");
+       Y = scanner.nextInt();
+        System.out.println("请输入Z的值");
+       Z = scanner.nextInt();
+       S = X*X*X+Y*Y*Y+Z*Z*Z;
+        System.out.println("这三个数的立方和为："+S);
+    }
