Hello,
Here is a simple program using ALV OO.
For OOALV,we <b>define a container</b>.Generally we use a <b>custom container</b>.The class used is <b>cl_gui_custom_container</b>.In the layout of your screen,make a custom container (icon with C written) and name it <b>CONTAINER</b> (in caps).Now create the container by going to the PATTERN button->ABAP objects.
We can now attach a control to the container.ALV,text editor,picture control are different types of controls.For ALV,we use the class <b>cl_gui_alv_grid</b>.Again you can create an instance by using the pattern button.The container name is given as the parent of the ALV in the constructor method.
We can use several methods of the ALV class to display data and for various functionalities.To display the data first time,we use <b>SET_TABLE_FOR_FIRST_DISPLAY</b> method.You can go to se24,type CL_GUI_ALV_GRID and click DISPLAY button.There you can see all the methods and attributes of the ALV class which you can use.
