This way, we can thoroughly test that functionality in one place and if any fixes or future changes are needed, they are done in that one module instead of multiple places in the code. In general the access-modifier can be public, private, or protected. So if the above method was in a class named MyMath, we would call it as: MyMath.calculateAverage(100, 50); The main method, which is where a Java program always starts executing, is a static method because when it starts, there are no instances of any classes yet. The idea of modularity is closer to using packages and JAR archives. credit by exam that is accepted by over 1,500 colleges and universities. In her first book, Learning Modular Java Programming, the reader explores the power of modular programming to build applications with Java and Spring. Before, we discuss about JVM lets see the phases of program execution. The following are some conventions we use to create a module: What does module-info.java contain? The course starts by diving deep into advanced Object Oriented concepts like inner classes, object composition, encapsulation, and polymorphism which will be demonstrated through a simple extension to a vehicle modeling example. This way, all the modules will be compiled and placed in their corresponding directories under the directory provided by the -d option. The book assumes some previous programming experience in Java 8 or earlier, familiarity with the basic Java types such as classes and interfaces, as well as experience in compiling and executing Java programs. When completed, the user should be able to enter a year and then click the OK button, enter a month and then click the OK button, and enter a day and then click the OK button to determine if the date is valid. Please use run.bat for Windows and run.sh for Linux. It helps to create modular programs and reusable code. To unlock this lesson you must be a Study.com Member. Java provides many packages with classes and methods for the typical functionality such as storing data in different data types, reading/writing data to console and files, math functions, etc. It builds on the material about abstractions and specifications covered in the earlier part of the book.
