I followed this up this discussion but it didn't help much Run Program from IntelliJ with Command Line File InputДЄlso, I trid the EXACT same thing (I guess.) in another computer and it worked, but in my personal computer I have a newer version of Intelij and some little things are different.

You can see the API documentation here.I'm trying to run a Java code using on Intelij IDEA passing a. Introduction to jGRASP - opening files, compiling and running programs, adding line numbers, generating the control structure diagram (CSD), and running prog. More often than not, you will be using API files in your code. The Java API is very extensive, contains classes which can perform almost all your programming tasks right from Data Structure Manipulation to Networking. The java.lang package is imported by default for any class that you create in Java.

While creating a package, care should be taken that the statement for creating package must be written before any other import statements.

Hence you were able to execute assignments earlier. When a package name is not specified, a class is in the default package (the current working directory) and the package itself is given no name.To avoid naming conflicts packages are given names of the domain name of the company in reverse Ex: com.guru99.Step 3)Execute the code using the command java p3.c3 Packages вЂ“ points to note: Compile the file using the command javac вЂ“d.

Import p1.* //imports classes only in package p1 and NOT in the sub-package p2 JFrame f = new JFrame // without fully qualified name. Import // here only the JFrame class is imported import .* // * signifies all classes in this package are imported Once imported, you can use the class without mentioning its fully qualified name. Instead, it is recommended you use the import statement.

To create an object of a class (bundled in a package), in your code, you have to use its fully qualified name.Д®xample: object = new () Д«ut, it could become tedious to type the long dot-separated package path name for every class you want to use. An illustrative screenshot is provided below. This is how the package is executed and gives the output as вЂњm1 of c1вЂќ from the code file. Go to Build -> Run Arguments, which is a checkbox youll need to select. This should cause a new text box, labeled Run Arguments, to appear just above the box containing code. Click on the Run Arguments check box (so that a check mark appears in it). On the menu bar of jGrasp, left click on Build. the package name followed by the sub-package name followed by the class name вЂ“ java p1.p2.c1 Using Command-Line/Run Arguments in jGrasp Heres how. Step 9) To execute the code mention the fully qualified name of the class i.e. Then we will modify our code as package p1.p2 ДЄs seen in below screenshot, it creates a sub-package p2 having class c1 inside the package. Step 7) Now letвЂ™s say you want to create a sub package p2 within our existing java package p1. Internally, jGrasp performs this by running javac, though it hides this detail from you. In our case file will be saved in parent directory which is C DriveДЇile saved in parent directory when above code is executed. Once your code is written, you can try to compile it. Step 6) Compile the same file using the following code javac вЂ“d. When you open the java package p1 inside you will see the c1.class file. Step 5) When you execute the code, it creates a package p1. The вЂњ.вЂќ operator represents the current working directory. This command forces the compiler to create a package. Next tutorials will provide you a fast track Java programming.

Go to download a complete JGRASP tutorial in PDF (on the left menu) or download thetutorial in zip file. JGRASP also can be used for other languages development tool such as Ada, C and C++. Step 4) Now we have to create a package, use the command javac вЂ“d. However JGRASP still lack many features though very nice and simple IDE.
