How to access Java package from another package

You can understand it using an example where a Boss class is defined in payroll package.

package payroll; public class Boss {    public void payEmployee(Employee e) {       e.mailCheck();    } }

if the Employee class is not in the payroll package? The Boss class must then use one of the following techniques for referring to a class in a different package.

• The fully qualified name of the class can be used. For example −

payroll.Employee

• The package can be imported using the import keyword and the wild card (*). For example −

import payroll.*;

• The class itself can be imported using the import keyword. For example −

import payroll.Employee;

A class file can contain any number of import statements. The import statements must appear after the package statement and before the class declaration.
