Right click on this object and select an instance method to run. You will see a new object appear at the bottom of the BlueJ window.
It may seem hard to believe that you're reading a different source code than the one producing the error, but it's definitely possible, and especially for new Java programmers. Select the new ClassName tab (the first in the drop down menu) Enter a name for this instance.

Hello, I am experiencing a lot of bugs with Greenfoot. My question is, How can i send it to my friend (knows nothing about java.) so he can run it by simply double clicking. The packaged class has not been referenced correctly using an import declaration. I made a program, compiled and ran it in bluej.The parameters used do not match a method's signature.This means we are able to successfully compile and run a simple java program.
It should print the output 'Hello World' on the screen. Also, underscores may or may not be necessary, so watch out for code that use them when they shouldn't be used or vice versa. Run the Java program: On the command prompt use the command 'java PrintHelloWorld' to run the program. Misspelling a class or method name. Remember that Java is case sensitive and spelling errors are not corrected for you. OBS wont work with world of tanks, i get a black screen, i hear the sound but no graphics, just black.I try to use the game capture.There are some pretty simple checks you can do to see where your problem is. Trying to use a variable without declaring it. It can be pretty frustrating when your quad won't start and all you want to do is hit the trails.
