Thread: Can anyone explain this code for me

Hi I am new to java, I have a bit of code that I would like explaining, stuff like what are the methods what are the variables what are the arrays, and what the code is doing. Any help would be appreciated. Thanks

public DetectorArray constructArray2(Gate1D timegate, boolean diagonals, boolean allowbad) {
 
	// Some variables
	boolean valid,fail,pileup,veto;
	double sum, max, theta, phi;
	long t;
 
 
	DetectorArray result = new DetectorArray();
 
 
	ArrayList cclist[] = new ArrayList[24];
	for(int i=0;i<cclist.length;i++){
	    cclist[i]= new ArrayList<Detector>(0);
	}
	for( Detector ge: event.clos.ges){
	    if(timegate.passes(event.stamp-ge.time)){
		((ArrayList<Detector>)cclist[ge.number/4]).add(ge);
	    }
	}
 
 
	for(int i=0;i<cclist.length;i++){
 
	    switch (cclist[i].size()){
	    case 1:
		// Single detector hit case
		// Pull out the hit
		Detector ge = ((ArrayList<Detector>)cclist[i]).get(0);
		// Create and store the new detector object
		if((!ge.fail && !ge.piledup && !ge.vetoed ) || allowbad)
		    result.ges.add(new Detector(i+16,(i/12)+4,ge.theta,ge.phi,ge.e,ge.time,1,ge.valid,ge.fail,ge.piledup,ge.vetoed));
		break;
		}
		}
 
			for( Detector ge: event.ph1s.ges){
			    if(timegate.passes(event.stamp-ge.time))result.ges.add(ge);
			}
			return result;
