Strings are always enclosed in double quotes.

Of course if we wanted to set that value to a variable we’d have to set the type to be int because it returns a number. So we can do something like String dot length and it will return the length of the string. If you’ve done any other coding you probably know about functions, well methods are pretty much the same thing except they exist within an object. All this means is String is actually an object that we can call methods on. Notice String is capitalized, that’s because its a complex data type while the others are known as primitives. Here’s a list of the more common data types, int holds a number, float holds a decimal, boolean holds true or false, char holds a single character, and String. The first word String is the data type which specifies the type of data pickupLine will hold. Let’s break this down, In Java we use camel case when declaring variables, so no spaces, but the second word L is capitalized. Lets do an example, here we set the variable pickupLine equal to “Hey girl, you had me at hello world”. Variables are containers, they hold stuff in your program, from strings, which are usually words and sentences, to numbers and more complex objects.

There goes the flannel, you're so close, feeling overloaded… with information? In this lesson we’re going to make shit happen, but first let’s learn a little bit about variables in Java. Support our courses! Buy the Pickup Line App!
