We can call the method in different ways with the help of one import parameter. This strategy will be valid for more than one import parameter also. One of the parameters must be mandatory. In the following example we have a method m_test which contains an import parameter i_inp. Now we are calling that method in different three ways as follows.

               obj_test->m_test( i_inp = 7 ),

The output is as follows:
