Creating Java Integrated Development Environment (IDE) In C#

First, check if project location and project name are not empty strings. Then, check whether "Create Java Class" checkbox is checked or not. If it is not checked, then just create project without .java source file.

First, create your Java project file (projectfile = projectname + ".slvjproj";). Then, we create this file and start to write that file by using XmlWriter class.

We will write Project Name, Project Location Folder, Project type tags with its read values. Once we are done with this, we need to change the contents of file defaultprojloc.slvjfile

In this file, we will save current created/opened project name, location folder, project location file, project type.

If Create Java Class check box is checked then we will perform all action as above just adding following tags and info to it.where fname is entered java class file name

I am keeping track of created project, which means if Project is created without creating a java class (which means Create Java Class checkbox is unchecked) then CheckProjectType() function return 1 otherwise it returns 2(variable a is used for this). This is for creating file, adding tabs to tabcontrol, adding projectname & filename to treeview etc. in MainForm.cs file.

Consider you have already designed you main IDE.

Now event for clicking on File->New->New Java Application Project

First show the New java application dialog form.

Download the source code.

ReadCurrentProjectFileName() function returns the string as project file name by reading file \files\defaultprojloc.slvjfile by reading tag CurrentProjectFileName.

If CheckProjectType() is 2 then we will create create a file by reading JavaClassFile tag text from current project, add tab to tabcontrol with control of texteditor,changing text of MainForm, add projectname & file names to ProjectExplorerTreeView and then we will save that file.

New Java Class

Now we need a class form that creates a java class.To create class a java project it must be created or opened in IDE. Following is the form that creates or adds java class to current opened project in the application.

In file New_Class_Form.cs, we are reading Class Name, also reading Modifiers,Super Class etc. Once Finish button is clicked, the tab is added to tabcontrol with same as class name by just adding .java to the end of it, and returning this filename with full path(getCreatedFileName() function).

In MainForm.cs file, In File_New_ClassMenuItem_Click() event, we will get this file name (getCreatedFileName()) , read contents from texteditor which is added to tabcontrol by New_Class_Form.cs file, create this file and write these contents to file using StreamWriter class.

Finally adding tag <JavaClassFile> & <VisualFile> with text as created filename.

Also adding <MainClassFile> tag, this tag text is read when we want to compile a file.

Download the source code to view complete code of ide.

Following is the code when File->New->Class option selected

For other options like,

This is the same code as creating New Java Class, just create files with their own extensions.

<JavaClassFile>,<HTMLFile> etc. Once project is opened add Project Type, ProjectName, Project Location Folder to \files\defaultprojloc.slvjfile.

I am checking if FilenameToolStripLabel contains ‘\’ or not, if it contains it then read texteditor contents from current selected tab & write it to file from FilenameToolStripLabel.Text or here you can read files\files.slvjfile where contains all current opened project files with their full path.

Load Sample Project

First design your sample project form for selecting what kind of project want to create.

Creating sample project involves nothing but to create a Project file(.slvjproj), Project directory, creating sub directories in it(src,classes,srcclasses), creating project files(.java) in those directories, adding this created project information to \files\defaultprojloc.slvjfile & just call OpenProject function with created project file name.

These project files are located at Samples folder.

First let's define variables to store what files need to be read from Samples folder.

Here I defined notepad_files(notepad source file), notepad_2(source file name we want to create in/as project)

listBox1 is the control added to form (see above image).selected_item contain selected sample project name and projectfolder contains users project folder.

Here we are just performing actions the same way as we create new Java application projects with Create Java Class checkbox checked.

Compile & Run

Compiling using IDE means runnnimg commands through processes. But here to compile a java source file we don't need any window to show, we just need output of compilation such as errors & warnings. It is easy to create process. We need boolean value for whether processes are started or not for compilation.

Consider you are compiling your java programs using cmd, same as we are doing here.

e.g

cd C:\MyJava\Hello
javac.exe HelloWorld.java

Download the source code.

See following code;

Where EXE is application javac.exe with full path

WorkingDirectory is our source file directory(srcclasses)(above e.g C:\MyJava\Hello)

FileName is our main java source file which we want to compile (HelloWorld.java)

We need only one java source file to compile, you can provide more files.

The main source file is saved in the project file(.slvjproj) with tag <MainClassFile>. This file can be changed by going to Run->Main Class
