Java is a high-level, class-based OOP language developed as a general-purpose programming language intended to write once and run anywhere (WORA). Compiled Java code can run on all platforms without the need to recompile. This course has been delivered over four modules. Module 1 explores the Java Development Cycle and allows us to differentiate between JDK versions and development tools. You will learn about operators and basic syntax and write a simple program. In module 2, The concepts covered include strings, string methods, StringBuilder, data flow diagrams, decision-making, loops, arrays, and simple programs. Module 3 delves into classes and objects, inheritance and polymorphism, Lambdas, and exception handling. Finally, over module 4, we will work on two UML case studies, including the ATM simulation and Employee payroll system. We will also learn about version control and GitHub integration of the projects developed. Upon completion of the course, you will gain comprehensive Java programming knowledge and be able to write complex codes in a real-world scenario independently. You will gain extensive foundational skills to become an intermediate to advanced-level developer.
