title: I can't run a program on Blue J
body: <p>My programs on Blue J compile correctly and when I want to run it, the "run button" is gone. It is replaced with these buttons:</p>
  
  <p>-new A2_1()</p>
  
  <p>-void main(String[] args)</p>
  
  <p>-Open Editor          .......(letters in red color)</p>
  
  <p>-Compile          .............(letters in red color)</p>
  
  <p>-Inspect              ..............(letters in red color)</p>
  
  <p>-Remove          .............(letters in red color)</p>
  
  <p>************ It does that to all programs I am trying to run.********</p>
  
  <p>A2_1 is just the class name of the program. I will say again: I can compile it but CANNOT RUN IT. I have no further technical experience with BlueJ to fix this problem.</p>
  
  <p>If it helps:</p>
  
  <p>-I have the current JDK. 
  java version "1.8.0_11"
  Java(TM) SE Runtime Environment (build 1.8.0_11-b12)
  Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)</p>
  
  <p>-I have OS X 10.9.5</p>
  
  <p>This problem came after I changed something in my Mac. I was taking a programming class at the time and we were studying inheritance. And I needed programs to access other previous written programs in order to run. Upon request of the professor I changed something in my Mac that deals with folder locations. That is all I remember.</p>
