Method Java

A method is a way to teach the computer a new command.

A method should do one simple job, and should be written like a command, like turnRight, or printHello.

Methods are named with lowerCamelCase.

For example, we could teach the Karel (the computer) to turn right with a method written like:

private void turnRight()
{
    turnLeft();
    turnLeft();
    turnLeft();
}

Methods allow us to:

1. Break down our code into separate reusable parts
2. Make our code easier to understand
3. Avoid writing repeated code
4. Simplify our code
