Here is an example use case for the wildcard.

gistfile1.java

protected ArrayList<String> wildWithInpAtBack(String inp,int ngramLength){
		ArrayList<String> out = new ArrayList<String>(ngramLength);
		for(int i=0;i<ngramLength-1;i++){
			out.add(i, FirstSentSum.WILDCARD_STRING);
		}
		if(inp.indexOf(" ")!=-1){
			for(String sepI : inp.split(" ")){
				out.add(sepI);
			}
		}
		else
			out.add(ngramLength-1, inp);
		return out;
	}

private useWildcard(){		  // Or here is a better example. I simply fill the rest of this sentence with ngrams that link together

String[] wordsSoFar  = strBld.toString().split(" ");
		String justAdded= wordsSoFar[wordsSoFar.length-1];
		while(  strBld.length()<sumLeng   ){ 
			  for(Map.Entry<ArrayList<String>, Double> elem : list){	// OMG This may read through the entire library	
				  if(elem.getKey().size()>1){
					if(localCompareObj.compare(elem.getKey(),wildWithInpAtFront(justAdded))==0){
						elem.getKey().remove(0);// If we dont do this then the TopNE[0] will appear twice
						strBld.append(printArray(elem.getKey()));
						wordsSoFar  = strBld.toString().split(" ");
						justAdded= wordsSoFar[wordsSoFar.length-1];
					}
				  }
			  }
			  strBld.append(" ");
			if(strBld.length()>sumLeng){ //Remove words that done fit and we are done
				out = strBld.toString();
				out = out.substring(0,sumLeng-1);
				out = out.substring(0,out.lastIndexOf(" "));
				break;
			}
			
		  }
