Contains method case-insensitive without major code changes?

Question

Is there a way to ignore the case for the contains() method but at the same time leave the code snippet more or less the same?

/**
 * This method returns a list          


        

Answer 1

Make both strings lowercase(or uppercase)

public ArrayList<String> wordsContaining(String text)
{
    int index = 0; 
    text = text.toLowerCase();
    ArrayList<String> wordsContaining = new ArrayList<String>();      
    while(index<words.size())
    {
        if((words.get(index).toLowerCase().contains(text)))
        {
            wordsContaining.add(words.get(index));
        }
        index++;
    }
    return wordsContaining;
}
