What is the output of the following code snippet?public class Example ...
The 'sum' method in the code snippet is overloaded with two versions: one that takes two integers and another that takes two doubles. In the 'main' method, 'sum(3, 4)' is called, and since the arguments are integers, the first version of 'sum' is invoked, returning the sum of 3 and 4, which is 7.

What is the output of the following code snippet?public class Example ...
The output of the given code snippet is 7.
Explanation:
- The code snippet defines two methods with the same name "sum", but with different parameter types.
- In the main method, the sum method is called with two integer arguments: sum(3, 4).
- Since there is a method with matching parameter types (int), the compiler selects the method with int parameters for the method invocation.
- The selected method calculates the sum of the two integer values (3 and 4) and returns the result.
- The returned result (7) is then assigned to the "result" variable.
- Finally, the value of "result" (which is 7) is printed using the System.out.println() method.
Key Points:
- The code snippet demonstrates method overloading, where multiple methods can have the same name but different parameter types.
- The method with matching parameter types is selected for the method invocation based on the arguments passed.
- In this case, the method with int parameters is selected because the arguments passed are integers.
- The selected method performs the addition operation and returns the result, which is then printed.
Therefore, the output of the code snippet is 7.
