Hey guys,
I am a coding school student and have been learning Java for the last three months every day for more than 8-10 hours!
It's already been over 5000 hours since I studied programming.
(Check out my insta! @agilemeadow)
Still a noobie, but for those who want to start the programming journey, I brought what I did in my very first month.
I would be very happy to hear your new idea for improving my must-know list.
- Data types
- Variables (regional variable, member variable, static variable)
- Operators
- Control statement (condition statement, repeat statement)
- Auxiliary control statement (break, continue)
- Call Methods (Call by Value, Call by Reference)
- Arrays
- classes, objects, constructors, methods
- Access Controllers
- Date, Timestamp, Calendar
- String-related classes (String, StringBuffer, StringTokenizer)
- Inheritance (Member variable, method, constructor)
- Abstract classes, interface
- Collection, Generic
- List, Map
- Transform data type
- Basic data type conversion ex) double <---> int
- Data type conversion using a wrapper (basic data type <---> reference type)
- ex) int <---> String Wrapper Class (Boxing and Unboxing)
- int n = Integer.parseInt("20");
- Reference Type Transformation
- Exception handling
- Thread
- java.io.* (BufferedReader, FileReader, FileWriter, File)
- java.net.* (Socket Communications)
