Saving, Compiling and Running one Application

Follow the procedures outlined listed below to save, compile, and also runyour Java program.These instructions provide only the minimum information thatyou must compile and also run the instance program because that this lesson.For an ext information around the compiler, the interpreter,and structuring and managing her programming environment,see the ideal lesson inThe Java advance Environment.Saving a Java ProgramYou can use any type of editor or word processing programto create and edit a Java program,as long as it can save documents in ASCII format.Java programs should be conserved in a file whosename ends with the .java extension, sousing her favorite ASCII editor, enter the programexactly together it shows up on the an initial pageof this lesson and save the regimen to a file namedDateApp.java.Compiling a Java ProgramHaving produced your Java program, you have to compile her programusing the Java compiler before can you run it.If girlfriend have any type of problems, seeTroubleshooting Compiler Problems.The Java compiler equates Java source code right into Java bytecodeswhich are materials of a machine-level language because that the Java online machine.Java bytecodes room interpreted and also executed through the Java interpreter.When girlfriend compile a Java resource file, the compilercreates a paper with the .class extensionin the exact same folder as the resource file.The compiler name the result .classfile after the class characterized in the source file.For example, when you compile the DateApp course you createdabove, the compiler surname the resulting class document DateApp.classafter the class, regardless of the surname of the source file.Even if you were to conserve the DateApp class to a sourcefile called Wow.java, the compilerwould still produce a file named DateApp.class.By convention, to minimize confusion, Java resource files are called for the class defined within.Running a Java ApplicationNow, you deserve to run your application utilizing the Java interpreter.The regimen should display the present date and time.If friend have any type of problems, seeTroubleshooting Interpreter Problems.See AlsoCompiler guy PageInterpreter guy Page
