Open C:\Users\YOUR_USERNAME\ in Windows Explorer and delete the folder named. Before doing this, make sure you know where on your computer your Java code is saved, because jGRASP will forget which files and folders you have open. To make it forget about the old path and stop displaying this error message, you'll need to delete your jGRASP workspace and create a new default one. Once jGRASP has seen a file with a non-English path, it will remember it, even if you've renamed the folder.
Until this bug is fixed in jGRASP, we recommend only storing your Java files in folders with English names. This seems to happen after opening and closing a file whose path contains non-English characters. Some Windows users who have their OS configured with a non-English primary language encounter an "unable to encode text using charset us-ascii" error when closing jGRASP.
(Thanks to former TA Eric Spishak for this tip!) 'unable to encode text using charset us-ascii' errors In the text box that becomes available type in -J-Duser.language=en and click "OK". Then, click the black "button" under "FLAGS or ARGS" and next to "Compile". In the settings box that pops up, click the "Flags / Args" tab (in the lower row of tabs). To fix this problem, follow these steps in jGRASP.Ĭlick "Settings" -> "Compiler Settings" -> "Workspace". Some users who have their OS configured with a non-English primary language cannot properly see the compiler errors in jGRASP.

In the textbox labeled 'Document' put the following V1javadoc options.txt -d V2The first is the documentation that can be printed, the second is the source code with line numbers on the left. Follow the instructions on this page to download and set up jGRASP. Javadoc, reads your source code (A19002.java) and creates at least two files A19002.html and /src-html/A19002.html. JGrasp: We will be using the Java development environment jGRASP in this course.
JGRASP JAVA DOWNLOAD HOW TO
I couldn't figure out how to get jGrasp to automatically add the imports, so I just typed those in then it compiled and ran fine. If you think this applies to you, you can safely skip the JDK section of this guide, although you may find that you need to come back and complete it anyway. I didn't really have much clue what I was doing with jGrasp I just created a test project, create a new Java file, and typed in a 'Hello World' application subclass.
JGRASP JAVA DOWNLOAD SOFTWARE
Some users already have the JDK installed on their computers, because of other software that they use that is written in Java. Follow the instructions on this page to acquire the JDK. JDK: The Java Development Kit (JDK) includes the compiler that you will need for compiling and running Java programs.
JGRASP JAVA DOWNLOAD INSTALL
You will need to download and install two pieces of software for this course: the Java compiler (known as the JDK) and a Java development environment called jGRASP.
