Fields

Classes contain zero or more fields.

Fields are like variables except they don't live in a method, they are attached to instances of the class they are a part of.

To declare a field in a class you say the type of the field, a name for the field, and then a ;.

class Muppet {
    String name;
}

One way to think about it is that when you say new Muppet(), Java makes a box big enough to hold all of the fields that a muppet needs.¹
