I am trying to self teach myself to learn Java programming. Will someone please help me with this program. I getting confused about encapsulating. If I am comprehending what I am reading in my Java book, encapsulate means to start my properties with private so they can't be change by the client. Am I correct so far? Also, I know string means, whats inside the " ". With that said, will someone tell me how to go about coding the rest of this program contain in this post? When I run the program, I get error message:
/**Write a program that creates Boolean, Character, Byte, Short, Integer, Long, Float, and Double objects to encapsulate eight values supplied as command-line arguments. Display the string equivalent of each objects.
*/
2nd question: When I use the word properties as a designation in my question above, can that designation be interchangeable with the word variable?
