Systems Analysis and Design - assignment ExampleUnlike C++, which combines the syntax for structured, generic, and object-oriented programming, Java was built almost exclusively as an object-oriented language. tout ensemble code is written inside a single out, and everything is an object, with the exception of the intrinsic data types (ordinal and real numbers, boolean values, and characters), which ar not classes for performance reasons.Java uses similar observeing methods to C++. There are three different agencys of comment a single line tendency marked with two slashes (//), a multiple line style opened with a slash asterisk ( ), and the Javadoc commenting style opened with a slash and two asterisks ( ). The Javadoc style of commenting allows the user to run the Javadoc executable to compile documentation for the program.Source rouses must be named after the semi in the worldly concern eye(predicate) class they contain, appending the suffix .java, for example, HelloWorld .java. It must first be compiled into bytecode, using a Java compiler, producing a consign named HelloWorld.class. Only then can it be executed, or launched. The java source file may wholly contain one public class but can contain multiple classes with less than public access and any number of public inner classes.A class that is not declared public may be stored in any .java file. The compiler will generate a class file for each class defined in the source file. The name of the class file is the name of the class, with .class appended. For class file generation, anonymous classes are treated as if their name were the concatenation of the name of their enclosing class, a $, and an integer.The keyword public denotes that a method can be called from code in other classes, or that a class may be used by classes outside the class hierarchy. The class hierarchy is link to the name of the directory in which the .java file is located. The keyword motionless in front of a method indicat es a static method.
