+Write the method
+
+middle
+
+...which takes three integers as parameters. The method returns the middle of the numbers in order of magnitude.
+
+
+
+
+Example method calls:
+public static void main(String[] args) {
+    System.out.println(middle(1, 3, 2);
+    int mid = middle(8, 9, 7);
+    System.out.println(mid);
+}
+
+Program outputs:
