Can you explain what defining a function in Java means and how it is described?

In Java, a function is usually called a method and is described inside a class. A method is a block of code that performs a specific task and can accept parameters and return a result.

The declaration of a method includes:

• Access modifiers (e.g., public, private)
• Return type (e.g., int, void)
• Method name
• List of parameters in parentheses
• Method body in curly braces

Example of a method that returns the sum of two numbers:

public int sum(int a, int b) {
    return a + b;
}
