Shorten If Statement

Hi I am wondering if there's a way to make the following less redundant. Where 'ones', 'twos', 'threes', etc. are instance variables. (The switch statement doesn't allow them to be case arguments).

private int methodX(){

   int consec=0;

    if(ones==1){
        consec++;
    }
    if(twos==1){
        consec++;
    }
    if(threes==1){ 
        consec++;
    }
    if(fours==1){
        consec++;
    }
    if(fives==1){
        consec++;
    }
    if(sixes==1){
        consec++;
    }
    if(consec>=4){
        return 30;
    }
    else {
        return 0;
    }
}
private int ones;
private int twos;
private int threes;
private int fours;
private int fives;
private int sixes;
