What are some examples of functions in Java?

In Java, functions are defined as methods. For example, a simple function to add two numbers could look like this:

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

Can you show me a function that returns the maximum of two numbers?

Sure! Here's a function that returns the maximum of two numbers:

public int max(int a, int b) {
    return (a > b) ? a : b;
}

What about a function that checks if a number is even?

Here's a function that checks if a number is even:

public boolean isEven(int number) {
    return number % 2 == 0;
}

Can you explain how to use a function with parameters?

Certainly! When you define a function, you specify parameters in the parentheses. For example:

public void greet(String name) {
    System.out.println("Hello, " + name);
}

You can call this function with a name as an argument.
