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.
