Multithreading: Core Java provides powerful features for concurrent programming. Understand concepts like try-catch blocks, multiple catch blocks, and exception hierarchy. Memory Management: Java manages memory automatically, but understanding concepts like garbage collection, stack and heap memory, memory leaks, and object lifecycle will help you write better-performing code.Įxception Handling: Learn how to handle exceptions gracefully to ensure efficient error management and graceful program execution. Java Development Kit (JDK) Tools: Understand the usage of important JDK tools like javac (Java compiler), java (Java Virtual Machine), jar (Java Archive), javadoc (generating documentation), and debugging tools like jdb. Learn how to leverage these libraries to perform tasks like input/output operations, collections, networking, date/time manipulation, and more. Java APIs: Familiarize yourself with commonly used Java APIs such as java.lang, java.util, java.io, and. Learn about variables, data types, operators, control structures (if-else, switch-case), loops (while, for), and exception handling. Java Syntax: Mastering the syntax is essential to write efficient Java code. You should learn concepts like classes, objects, inheritance, polymorphism, and encapsulation. Object-Oriented Programming (OOP): Understanding the fundamentals of OOP is crucial for Core Java.

To excel in Core Java, you should focus on acquiring the following skills:
