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;
}
