GLProfile.isGL2Available() equivalent for current jogl code

I'm updating the jogl libraries for a project that was last updated in 2011 (https://code.google.com/p/g3d-editor/). Obviously, the APIs have changed, but most of the updates for this project only required me to add "gl" as a parameter to some methods that were called.
The last thing that still gives me errors is this code:

System.out.println("GL2: " + (GLProfile.isGL2Available() ? "Yes" : "No"));
System.out.println("GL3: " + (GLProfile.isGL3Available() ? "Yes" : "No"));
System.out.println("GL3bc: " + (GLProfile.isGL3bcAvailable() ? "Yes" : "No"));
System.out.println("GL4: " + (GLProfile.isGL4Available() ? "Yes" : "No"));
System.out.println("GL4bc: " + (GLProfile.isGL4bcAvailable() ? "Yes" : "No"));

the GLProfile methods aren't available anymore, so I'm not sure what to use instead.
I found that there is GLProfile.isAvailable(String profile), should I use that?

yes, i.e. w/ GLProfile.GL2 as an argument.

Sven is right:

System.out.println("GL2: " + (GLProfile.isAvailable(GLProfile.GL2) ? "Yes" : "No"));
System.out.println("GL3: " + (GLProfile.isAvailable(GLProfile.GL3) ? "Yes" : "No"));
System.out.println("GL3bc: " + (GLProfile.isAvailable(GLProfile.GL3bc) ? "Yes" : "No"));
System.out.println("GL4: " + (GLProfile.isAvailable(GLProfile.GL4) ? "Yes" : "No"));
System.out.println("GL4bc: " + (GLProfile.isAvailable(GLProfile.GL4bc) ? "Yes" : "No"));

Edit.: You could have used "final GL gl = GLContext.getCurrentGL();" instead of passing GL instances. GLShader and GLUniform could probably be replaced by some JOGL classes (GLUniformData, ShaderCode, ShaderProgram, ShaderState, ShaderUtil). Using display lists isn't a good idea, the speed up isn't consistent across platforms and it is badly implemented in some drivers.

@Sven - thanks for the parameter tip, didn't know about the constants, I just hardcoded them.

@gouessej - all that is in the future and if I ever get around to learning that stuff. I've never done anything graphical, so it's going to take a while.
The GL parameter is being passed all around the code. I didn't make it that way, I only made minor fixes and alterations to it to keep it up to date.
