In the above code, if the simpleMethod() method received a double or integer value, the resulting output is "Method receives double parameter". Explain how Java can promote one data type to another when a parameter is passed to a method.
What will be an ideal response?
When passing parameters to a method, Java can promote one data type to another. For example, if a method has a double parameter and you pass it an integer, the integer is promoted to a double. The order of promotion is double, float, long, and int. Any type in this list can be promoted to any type that precedes it.
When you call the method with the double argument, the method works as expected, and when you call it with an integer argument, the integer is cast as (or promoted to) a double.
