The keyword super is used for the following cases: Call the superclass method The “super” keyword is used to call parent class method. Sometimes a subclass and superclass have the same method name, so for resolving ambiguity purpose the “super” keyword is used. Call the superclass constructor The “super” keyword is used to access parent class constructor. This keyword can call both parametric and non-parametric constructors depending upon the condition. Use of “super” with variables This is happening when a base and derived class has same data members. So there is a possibility of ambiguity for the JVM.

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid." NAME DB 20 DUP(?) SNAME DB 20 DUP(?) Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters, bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0. For example, Letter 'h' Binary ASCII 01101000 68H 'H'…
