Code:

 public class TestScenario {

    public static void main(String args[]){
        int episode=0;
        String fileName="test.csv";
        String predicateFile="test.txt";
        Scenario newScenario=new Scenario();
        newScenario.setPredicatefile(predicateFile);
        //newScenario.initializeScenario(1,fileName,"John Hinkle Place",5);
        //newScenario.startScenario("Accelarate","doNothing");
    }

}

error:

Selection does not contain a main type.

Error screenshot:

But I clearly have a main class declared. Any suggestions on the mistake is helpful.

how `Selection` look like? – Youcef LAIDANI May 23 '17 at 21:59
@YCF_L am not getting your question. – vikky 2405 May 23 '17 at 22:00
Selection is not define in your code, is it a class or what? – Youcef LAIDANI May 23 '17 at 22:01

Right click your `TestScenario` class file in eclipse, select `Run As` , and select `Java Application`. This probably happened because you clicked that green play button, but did not check out what is on the selection . You can see it by clicking dropdown arrow next to that green play button. – Jimmy May 23 '17 at 22:01

Sounds like you tried to run a class called "Selection" when in fact you wanted to run "TestScenario". – Chris Parker May 23 '17 at 22:02
@ChrisParker nope i did not make that mistake. In fact I do not have a class called selection in the code. – vikky 2405 May 23 '17 at 22:03
@Jimmy Nope I did not use the green button. I did exactly what you suggested. – vikky 2405 May 23 '17 at 22:04
Then Click that 010 sign on tep left of eclipse. basically build it once and try again – Jimmy May 23 '17 at 22:05

Did you save the file? – Devendra Lattu May 23 '17 at 22:05
@DevendraLattu yes. – vikky 2405 May 23 '17 at 22:09
Right click on the folder where you put your main class then click on Build Path --> Use as Source Folder. Finally run your main file as java application. Hope this problem will be solved.
