List<String> arrayList = new ArrayList<String>();
for (String s : arrayList) {
if(s.equals(value)){
//do something
}
}
or
for (int i = 0; i < arrayList.size(); i++) {
if(arrayList.get(i).equals(value)){
//do something
}
}
But be carefull ArrayList can hold null values. So comparation should be
value.equals(arrayList.get(i))
when you are sure that value is not null or you should check if given element is null.
