To Automatic type conversions apply to overloading

Here is a Java Program to Automatic type conversions apply to overloading.

class OverloadDemo {
  void test() {
    System.out.println("No parameters");
  }

  // Overload test for two integer parameters.
  void test(int a, int b) {
    System.out.println("a and b: " + a + " " + b);
  }

  // overload test for a double parameter and return type
  void test(double a) {
    System.out.println("Inside test(double) a: " + a);
  }
}

Here is a Main Program to Run above Java Class

class Overload {
  public static void main(String args[]) {
    OverloadDemo ob = new OverloadDemo();
    int i = 88;

    ob.test(); 
    ob.test(10, 20);

    ob.test(i); // this will invoke test(double)
    ob.test(123.2); // this will invoke test(double)
  }
}

Output of Above Java Program
No parameters
a and b: 10 20
Inside test(double) a: 88.0
Inside test(double) a: 123.2
