Develop a multithreaded client/server application. The client will send a MyString to the server. MyString class consists of a string variable and an int variable for the length of the string.
Methods for MyString include the standard Java coding methods and reverseTheString, determineLength, and pickASub which takes two integers (the beginning and ending of the substring) and returns the substring. The server will set the length variable to the length of the string and send the object back to the client. The Client will print the MyString object.
Use ExecutorService and provide output statements showing the progress of the transaction on both the client and server sides.
You will also turn in a JUnit test class for MyString.
