1. Variables are fields in classes or structures. If there is no obvious initialization, the variable is created in a default state with a default initial value of 0.
2. The variables in the method must be explicitly initialized, otherwise an error will occur when using the variables.
Example
public class BedAndBreakfast {
// initialize to 10
public static int capacity = 10;
// initialize to false
private boolean full = false;
