Thread: Eclipse runs not the opened class! Why? :S

Hello!

Im a newstarter in Java, im writing the programs of "Java for Dummies". Im by the part, where you
read & write data from the hard disk. If I run the opened class, it brings no error message and in the console
I can see, terminated, but not the opened class, but an other one in the package. So the program actually doesn't do what it should.
Could somebody experienced help me?

It's impossible to say how you got to where you are without standing by, looking over your shoulder, but Eclipse's run behavior is sometimes confusing. If you're simply attempting to run the ListAllUserNames program by pushing the green "Run button," Eclipse may be running the last program run which was the ReadAndWrite program. You can see the list of programs in the Run Queue by selecting the drop down triangle next to the Run button, and you'll probably see that ReadAndWrite is at the top of the list.

The sure way to run the file you want to is to right click the file name in the Project Explorer and then select Run (or Run As . . .), then Java Application (if available). I don't have Eclipse in front of me so am going from memory, but I should be close enough to get you there. After completing these steps, the most recently run program should be at the top of the Run Queue and will be run the next time the Run button is pressed.

Why is this confusion occurring? Not sure. Maybe because there are two runnable files in the same project . . . Don't know.

Hey Greg,

it worked with Run As... ! Thank you for your help!

cheers

You're welcome. Glad to help.
