A method call is a way to execute a specific function or procedure defined within a programming language. When a method is called, the program temporarily pauses its current task to perform the actions specified in that method. This allows for organized and reusable code, making it easier to manage complex tasks. In many programming languages, a method call includes the method's name followed by parentheses, which may contain arguments or parameters. For example, calling a method named calculateSum might look like calculateSum(5, 10). This structure helps programmers break down problems into smaller, manageable parts.
