This beginner-level Java course is designed to build a strong foundation in core programming concepts using one of the world’s most widely used languages. It introduces learners to Java’s syntax, structure, and object-oriented principles while explaining how Java works through the JVM and the “Write Once, Run Anywhere” philosophy.
Students will learn about variables, data types, control flow, methods, arrays, strings, and the collections framework. The course also covers program structure, compilation and execution flow, and basic exception handling practices. Special emphasis is placed on writing clean, readable, and logically structured code.
By the end of this course, learners will be able to write small to medium-sized Java programs, understand object-oriented basics, handle common runtime errors, and confidently move toward more advanced topics such as multithreading, databases, and backend development.
This course is ideal for absolute beginners, students, and aspiring backend developers who want to start their programming journey with Java.
