(Java)... i. ii. 111. Implement the following tasks by using concepts of object-oriented programming Define and implement UML association, composition, aggregation with suitable example, separately. Also write their differences in table form. Suppose a file "ABC.txt" contains three integers separated by commas. Write a program that use the existing file, read the integers and display them in reverse order separated by spaces. Secondly, get string input from user and append an existing file. Finally, count the number of words in a file. Design an application called SwingArithmetics as shown below. The "CLEAR" button shall clear all the text fields. Other buttons shall perform the required operation on first two text fields and show in result. (Java)... i. ii. 111.
