systems design and development (java) TCA exam in two days

Not too sure what will be on this exam, but as someone who has been coding for more than 2 years I would say that it definitely helps to remember better if you write code as well as just revise, especially if you're not that good at java, writing out the syntax will help you understand it better

GUMI is right - you can learn coding ONLY by doing BOTH reading books, internet and listening to lectures on the one hand AND actual hands-on coding on the other hand - one OR the other will not teach you properly, and the coding has o be successful.

I am very dubious about having to learn even basic java in just two days, unless you are actually revising, and not learning for the first time (a lot of students think the two are synonymous!).

I would suggest that in the short time you have:

1. Read up core concepts like OOP and its advantages, variables (primitive and reference types [with the latter having 2 sub-types: [class variables and array type]), inheritance, arrays and array lists, data types (numerical [integer, short, double, long], String, boolean, etc.), methods (declaration and body), constructors, creating an object with the "new" keyword; public, private, static and final variables and methods, while and for loops - this should easily take up 8-10 hours.

2. After reading up each topic, practice coding by doing some exercises at the end of each chapter (most books on java have such questions e. g. Java Concepts, Big Java, Introduction to Java Programming.

Good luck!
