Important Concepts in Core Java..!
1.OOPS concepts- If there is not the clarity of basic oops concept then doing core java is not of much importance. Revise C/C++ and go through all the basic concepts of it.
2.File Handling- Important while handling the file online its very important in Java.
3. Strings- Very basic and important topics making bigger software's always need the help of basic functions of strings.
4. Exception Handling and Thread Handling- Concepts always build your career strong and basic concepts of why, where and how always make your life easier if you are a coder.
5. Collection Framework- Last but not least.Collection Framework is the demand of Industry.Gives you extra flexibility while using Collection Framework.Basic limitations of arrays will be solved by implementing these methods.
Other topics: Swings,Applets, Frames,Packages, Generics, Access Modifiers and other basic concepts (which you already have done in C/C++ like loops, initialization process),Classes and objects,Wrapper class, Command line arguments,Garbage Collection (which is just to understand the process, not worry about it)
There are many more topics you can go through to have a good look of Java but above are the necessary things you should learn thoroughly at any cost if you want to be a Java Developer.
If you are an engineer and want to join the IT, it is best to get a certification on programming languages. Below I will be mentioning the best java training institute and the best software testing training institute in Bangalore.
