About the Java Core course

Java is an object-oriented programming language known for running the same compiled code on any system with a Java Virtual Machine. Banks, e-commerce companies, enterprise software firms and Android developers use it widely, and Core Java refers to the language itself and its standard libraries, the base on which web frameworks and Android apps are built.

The 80-hour Core Java course begins with installing the JDK and writing, compiling and running programs in an IDE. You learn data types, operators, control statements and arrays, then spend substantial time on object-oriented programming: classes, constructors, inheritance, interfaces, abstract classes and polymorphism. Packages and access modifiers show how real projects are organised. You also handle checked and unchecked exceptions, work with String and StringBuilder, and use the Collections Framework with List, Set and Map. The final modules introduce multithreading, file input and output, and connecting to a database with JDBC. Each concept is practised through coding exercises, in the classroom at CADD centres or in live online classes.

Core Java is the starting point for careers such as Java developer, backend developer, Android developer and software tester. The logical next step is our Advanced Java course, which covers Servlets, JSP and web applications.

You will be able to

  • Install the JDK and write, compile and run Java programs in an IDE
  • Use data types, operators, control statements and arrays in Java
  • Apply OOP in Java: classes, constructors, inheritance, interfaces and polymorphism
  • Organise code in packages and use access modifiers correctly
  • Handle errors with checked and unchecked exceptions
  • Use String, StringBuilder and the Collections Framework: List, Set and Map
  • Write multithreaded programs, read and write files and connect to a database with JDBC

Who it is for

  • BCA, MCA, B.Tech and B.Sc. computer students
  • Beginners who want to start a career in software development
  • C or C++ learners moving to Java
  • Learners planning Advanced Java, Spring Boot or Android development

What you need

  • Basic computer skills; any earlier programming knowledge is helpful
  • Logical thinking and school-level maths
  • A Windows PC or laptop with at least 4 GB RAM and a stable internet connection for live online classes

Java Core course — FAQ

What is Core Java?

Core Java is the base of the Java language: syntax, object-oriented programming, packages, exceptions, strings, collections, multithreading, file handling and JDBC. Advanced Java and frameworks are built on it.

Can a beginner learn Java?

Yes. Java has clear rules and good error messages, which suits beginners. The course starts from installing the JDK and writing the first program, then builds up to OOP and collections.

How long is the Core Java course?

The Core Java course is 80 hours long. The counsellor will share batch timings for your centre or for live online classes.

Can I learn Core Java online?

Yes. CADD Training Centre runs Core Java in the classroom and as live online classes. You install the free JDK and an IDE such as IntelliJ IDEA, Eclipse or VS Code on your computer.

Will I get a certificate after Core Java?

Yes. Core Java learners get a CADD Training Centre certificate on completion. Its online verification, by QR code or code number, makes it easy to attach to job applications.

What is the difference between Core Java and Advanced Java?

Core Java covers the language and its standard libraries. Advanced Java builds web and enterprise applications with Servlets, JSP and frameworks such as Spring, and needs Core Java first.

What jobs need Core Java?

Core Java is the base for roles such as Java developer, Android developer, backend developer and software tester, after further practice with frameworks and projects.
