Welcome, Java novices! Today we're diving headfirst into the wondrous world of variables and types. Buckle up, because it's about to get real.
So, what is a variable, you ask?
A variable is like a box where you can store a value. It's like a labeled container that can hold a specific type of thing, like an int or a String. You can think of it like a labeled box with a specific size and shape, but instead of a box, it's a box of code.
And types? Well, types are like the different kinds of boxes you can use to store values. There's int, String, boolean, double, and more! Each one is like a different kind of box, with its own unique characteristics and rules.
Let's take a look at some examples, shall we?
Ints are whole numbers, like 1, 2, 3, and so on. They're perfect for storing counts, like how many apples you've got in your lunchbox.
Here's an example:
int myInt = 5;
System.out.println(myInt); // Output: 5
And that's it for ints! Simple, yet elegant.
Next up: Strings, the fancy pants of the variable world. Or if you're feeling particularly fancy, let's talk Doubles. And for the true masochists, let's get real crazy with Booleans.
