Lab Exercise 7.1 Instructions: Name your program as YourLastNameFirstlnitialLE71.java. From the code in LE 6.2, do the following 1. You will NOT be changing any of the logic in the code for LE 6.2 2. Create a separate class called Users. This class will have NO main() 3. Insert a default constructor in the Users class. This is a method that is empty and its header looks like this: public NameOfClass() 4. Except, for the main), take all the other methods in LE 6.2 and put them in the Users class 5. Transfer the fields (class-level variables) from LE 6.2 to Users 6. Strip the word static from the fields and the method headers in the Users class 7. Cut and paste the main) from LE 6.2 into your program file for LE 7.1 1. Create an object of the Users class 1. Format NameOfClass objectName = new NameOfClass() 2. Use that object for the method calls in the main 1. Format: objectName.methodName0) 8. Make sure both classes are in the same directory 9. To run both programs, you must run the class with the main)
