1) Create a single *.java file that contains the code below describing classes A, B and C. Notice that each class has its own Main method. Compile the file. (40 points).1.a) How many *.class files were generated? What are their names?1.b) Run all the *.class files and take screen shots of the output.———————————————————————————————————-class A{public static void main(String[] args){System.out.println('Testing class A');} }class B{public static void main(String[] args){System.out.println('Testing class B');} }class C{public static void main(String[] args){System.out.println('Application C entry point');} }-----------------------------------------------------------------------------------2) We want to change the structure of the application such that it runs fromonly one of the three classes. In other words, only one class will contain the Main method and the other two classes will not. These other classes will contain methods called something other than Main.2.a) Edit the *.java file that contains the description of the three classes to implement the above instructions. Make sure that there is only one method with name Main. The other two methods should have different names.2.b) Check the number of *.class files generated when you compile the application. How many did you find?2.c) Execute the application and take a screen shot of the output. Include it in your report.2.d) Change the contents of the methods in the three classes to produce different outputs. Compile and run the application. Take a screen shot and include in your report.General instructions:Your report should be uploaded in eCampus in MS Word or pdf document formats only. Do Not upload any graphics files in native formats (jpg, png, etc.)
