Core Java Programming from Scratch to Advanced

Install JDK 1.8 on Windows 7 to 10, download the JDK, set JAVA_HOME, and verify with java -version on the command prompt.

Write and run a hello world program in a text editor such as TextPad or Notepad++, covering editing, compiling, and running, with steps on classpath, system variable, and main method.

Learn the Java program structure via a class outline, covering class declaration, methods, the main method, System.out, and basic concepts like data types and access modifiers with practical examples.

Explore Java language keywords, including the 50 reserved words and their use as identifiers, with focus on deprecated and unused terms like go to and Const.

Explore variables, data types, scopes, and the String class in Java, including primitive and wrapper types, boxing/unboxing, and immutability with common operations.

Explore Java operators, including relational, logical, bitwise, shift, unary, assignment, and the ternary operator, and learn how expressions are evaluated and precedence rules.

Learn how to read user input from the console in Java using a Scanner, capturing names, ages, and salaries with nextLine and next methods, and properly closing the input stream.

Explore inner and anonymous classes in Java, including local and nested classes, outer private member access, and anonymous instances that implement interfaces or abstract methods without extends or implements keywords.

Explore what an exception is, its class hierarchy, and the difference between checked and unchecked exceptions. Learn to handle errors with try-catch-finally, throw/throws, stack traces, and create custom exceptions.

Explore the Java collections framework (JCF), its interfaces and implementations like hash map, tree map, and lists, and learn about iteration, concurrent modification exception, and sorting with comparator and comparable.
