Alternative to if else statement

I need to find an alternative way for this (if else statement) :

    if(representatives.indexOf(word) == -1){  

    else if(repeatWords.indexOf(word) == -1){  
        repeatWords.add(word); }


Try with contains as devid explained. contains is a function of list to checkout object contains or not. so you have to modify code like below:


    else if(!repeatWords.contains(word)){  
        repeatWords.add(word); }

It check if list don't contain object then add it. otherwise; everything seems ok!!.
