These files need to be saved in the folder/directory which you created in the previous step.Įxactly how you perform the download depends on which Web browser you're using.įor both Firefox and Chrome, you can right-click the above links and choose “ Save Link As.”, and then navigate to the target folder/directory and save.Įxactly how you do this depends on your particular configuration. There are two binary files which you need to download, listed below: Step 2: Download JUnit Installation Files If you're unsure of what to name this folder/directory, the name junit_setup will work. The exact name or location of the folder/directory doesn't particularly matter, though the folder/directory should be in a relatively permanent location which you can easily reference later on.įor example, if you have a USB drive which you carry between the lab and home, it'd be good to put this folder on the USB drive. Step 1: Create a Folder/Directory for JUnit Installation FilesĬreate a folder/directory where you will later save some JUnit installation files. Once jGrasp has been configured to use JUnit, you do not need to fo through these configuration instructions again. The instructions below accomplish just that. However, unlike with the JDK, jGrasp cannot automatically figure out where JUnit is, so we need to configure it to know where it can find JUnit. This is analogous to the fact that jGrasp has built-in support for the Java Development Kit (JDK), but it does not come preinstalled with the JDK. While jGrasp has built-in support for JUnit, it does not come preinstalled with JUnit. This guide covers two big things related to JUnit: The console displays 'Sum is: 13224' output that was generated by our Demo program.Testing in jGrasp Using JUnit Testing in jGrasp Using JUnit In this particular case, the output generated by the program simply goes to the Run I/O output console which is displayed asjGRASP's bottom window.

The byte code that you created when you clicked the Compile button, along with some Java library code, will get loaded into memory and then run through the Java Virtual Machine (JVM). java files):Ĭlick the Run button to have the computer perform the instructions in our program (or click Build and then click Run, or click control-r). You might need to switch the viewable files to All Files in order to see the Demo.class file (the viewable files is often set to show only the.

The byte code will be saved in a file named Demo.java. Translate the the Java source code into byte code by clicking the Compile button, or click Build and then click Compile (or control-b). Then click the Save button in the resulting dialog box. Now use the jGRASP editor to 'type in' your program, then save it to the disk drive as Demo.java (for this demonstration it is a better idea to copy the text from this page and paste it into jGRASP).Įnter the text supplied at the previous link 'enter the text from this page'. The example creates a Demo Java class.ĭouble click on the jGRASP icon to start jGRASP:īefore doing anything else, make sure that you navigate to the folder in which you are going to write your Java programs:Ĭlick File, click New, and then click Java to open an empty text window in the jGRASP editor:

Below is a quick example that shows how to edit, compile, and run a Java program with jGRASP. The jGRASP website also has a very good tutorial on using the IDE which you should read.

The jGRASP IDE can be downloaded for free from. A debugger allows the programmer to examine a program as it runs - the programmer can watch the flow instructions as they are processed by the CPU, and look at the contents of the variables as the program runs.

For example, the jGRASP IDE includes a editor for entering and modifying Java programs, runs the compiler to translate the Java program to byte code, and runs the program on the CPU via the Java Virtual Machine. An IDE brings together (integrates) several different tools used in the program development process. The use of an integrated development environment ( IDE) can help a programmer work through the steps of developing a program. Prev Introduction to an Integrated Development Environment (IDE) jGRASP
