strange output in J creator

Question

Hi I am putting together an assignment for school and am getting a very strange output from it. the program compiles fine, but I check the output it gives me this:

or  java [-options] -jar jarfile [args...]

Process completed.

I am not sure what I have done wrong here as it looks good by both my friend and myself.

The source code, (Bearing in mind the program is not yet completed) is here:

any help with this would be greatly appreciated,

Thank you

Answer 1

This issue occurs if the main class is not correctly configured, to fix it

Go to Project->Project Settings->In the run combo box select your main class and click ok.

If project settings is grayed out it means and you are creating the file in standalone mode and you cannot select the main class hence you have to create a new project.

BTW, JCreator is not a good IDE for java development and has many bugs. It is not open source. Switch to Eclipse of Netbeans or intellij Idea community edition at some point, you would never regret.

配置主类，删除所有.class文件，然后再次运行该程序。
