So I am running a Boggle Solver in java on the NetBeans IDE. When I run it, i have to quit after 10 minutes or so because it will end up taking about 2 hour to run completely. Is there something wrong with my code or a way that will make is substantially faster?
public void findWords(String word, int iLoc, int jLoc, ArrayList<JLabel> labelsUsed){
if(iLoc < 0 || iLoc >= 4 || jLoc < 0 || jLoc >= 4){
return;
}
if(labelsUsed.contains(jLabels[iLoc][jLoc])){
return;
}
word += jLabels[iLoc][jLoc].getText();
labelsUsed.add(jLabels[iLoc][jLoc]);
if(word.length() >= 3 && wordsPossible.contains(word)){
wordsMade.add(word);
}
findWords(word, iLoc-1, jLoc, labelsUsed);
findWords(word, iLoc+1, jLoc, labelsUsed);
findWords(word, iLoc, jLoc-1, labelsUsed);
findWords(word, iLoc, jLoc+1, labelsUsed);
findWords(word, iLoc-1, jLoc+1, labelsUsed);
findWords(word, iLoc-1, jLoc-1, labelsUsed);
findWords(word, iLoc+1, jLoc-1, labelsUsed);
findWords(word, iLoc+1, jLoc+1, labelsUsed);
labelsUsed.remove(jLabels[iLoc][jLoc]);
}
here is where I call this method from:
public void findWords(){
ArrayList <JLabel> labelsUsed = new ArrayList<JLabel>();
for(int i=0; i<jLabels.length; i++){
for(int j=0; j<jLabels[i].length; j++){
findWords(jLabels[i][j].getText(), i, j, labelsUsed);
//System.out.println("Done");
}
}
}
edit: BTW I am using a GUI and the letters on the board are displayed by using a JLabel.
