How to access Java package from another package

JavaJava Programming Java 8

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.
