Java, an object-oriented programming language, is the most widely used development language in the world today. It allows programmers to create objects that can interact with other objects to solve a problem. This course describes key features of Java and object-oriented programming, Java technology and the development environment, working with IDEs, and the product life cycle. It covers using object-oriented analysis, identifying problem domains and objects, defining criteria for recognizing objects, attributes, and operations, and designing and modeling a class. Defining a class, identifying class components, using variables, using a main method, identifying keywords, testing and executing a simple Java program, common causes of syntax errors, and the purpose and features of an IDE debugger are also explored. In addition, this course covers identifying the uses of variables and defining a variable's syntax, primitive data types, declaring, initializing, and using variables and constants, modifying variable values by using operators, and using promotion and type casting.
