+    public static void main(String[] args) {
+        double a;
+        a = 4.0;
+        a = 24;

+
+public class Example {

+Method parameters can also be of different types, for example:
+
+public class Example {
+    public static void main(String[] args) {
+        tempBetween(10, 30, 25.5);
+        tempBetween(-5, 5, -15.25);

+    public static void tempBetween(int min, int max, double temp) {
+        if (temp >= min && temp <= max) {
+            System.out.println("Temperature is between the given values!");
+        } else {
+            System.out.println("Temperature is not between the given values.");
+        }
+    }
+}
+Program outputs:
+
+Temperature is between the given values!
+Temperature is not between the given values.
