Hi Sandeep,

There is no method overloading in ABAP./ But there is something called a redefinition.

When you inherit a class from a super class, you can redifne a method. You cannot chnage the signature( Interface) of the method. It will remain the same as that of the super class.You must redefine a method in the same visibility section in which it appears in the superclass.

Eg.

CLASS C_SUPER_CLASS DEFINITION .

PUBLIC SECTION.

METHODS: DRIVE ,

STOP.

PROTECTED SECTION.

DATA SPEED TYPE I.

ENDCLASS.

CLASS C_SUPER_CLASS IMPLEMENTATION.

METHOD DRIVE.

SPEED = 0.

WRITE: / 'Bike speed =', SPEED.

ENDMETHOD.

ENDCLASS.

CLASS C_SUB_CLASS DEFINITION INHERITING FROM C_SUPER_CLASS.

PUBLIC SECTION.

METHODS DRIVE REDEFINITION.

ENDCLASS

CLASS C_SUB_CLASS IMPLEMENTATION.

METHOD DRIVE.

SPEED = SPEED + 10.

WRITE: / 'Bicycle speed =', SPEED.

ENDMETHOD.

ENDCLASS.
