Using Classes and Objects

object

an entity or data type that we create in java.

class

they contain instance fields or data that belong to the object and methods that are used to manipulate the data

Precedence

the order of operations in java

static variable

the variable belongs to the class itself, and is initialized only once at the start of the execution

immutable

the state of the object doesn’t change since it has been initialized

Method usage

when using methods of a class, remember the parameters used to call the method need to match the data types of the arguments of the defined method
