What are some examples of methods in Java?

In Java, methods are blocks of code that perform a specific task. For example, a simple method could be:

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

This method takes two integers as parameters and returns their sum.

Can you show me a method that returns a string?

Sure! Here's an example of a method that returns a string:

public String greet(String name) {
    return "Hello, " + name + "!";
}

This method takes a name as a parameter and returns a greeting message.

What about a method with no return value?

A method with no return value is called a void method. Here's an example:

public void printMessage(String message) {
    System.out.println(message);
}

This method prints a message to the console and does not return anything.

Can you explain method overloading?

Method overloading occurs when multiple methods have the same name but different parameters. For example:

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

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

Here, both methods are named add, but one works with integers and the other with doubles.
