Java Generics: Java generic classes and generic methods allow the programmers to specify, with a single class declaration, a set of related types and with a single method declaration, a set of related methods. Using the concept of generics, user can write a generic method sort for sorting objects array then call this method with String arrays, Integer arrays, Double arrays and more for sorting the elements of the array. The user can create a single generic method and call it with arguments of different types. The compiler handles the methods calls appropriately based on the types of arguments passed to the generic method. Generic static method: Methods that introduce their own type parameters are called as generic method. List of type parameters included inside the angle bracket appears before the method's return type. Generic static methods in Java are are type-erased on compile time and changed to its Bound type. The bound type is the class mentioned inside diamond bracket or Object type.

Program Plan Intro

Java Generics:

Java generic classes and generic methods allow the programmers to specify, with a single class declaration, a set of related types and with a single method declaration, a set of related methods.

Using the concept of generics, user can write a generic method sort for sorting objects array then call this method with String arrays, Integer arrays, Double arrays and more for sorting the elements of the array.

The user can create a single generic method and call it with arguments of different types.

The compiler handles the methods calls appropriately based on the types of arguments passed to the generic method.

Generic static method:

Methods that introduce their own type parameters are called as generic method.

List of type parameters included inside the angle bracket appears before the method's return type.

Generic static methods in Java are are type-erased on compile time and changed to its Bound type. The bound type is the class mentioned inside diamond bracket or Object type.

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'…
