#Day26 of learning Java with @ShradhaKhapra_ @ApnacollegeX Today I explored ArrayList — a dynamic array that grows as needed. Loved how it simplifies working with collections compared to regular arrays! #Java #CodingJourney #100DaysOfCode #buildinginpublic

If you sometime write Java code similar to this: List<String> stringList = map.get(key); if(stringList == null) { stringList = new ArrayList<String>(); map.put(key, stringList); } stringList.add(newElement); You could express the same functionality with just a single

if ArrayList is dynamic then what if we give an initial capacity to it? lets bifurcate the constructor > for capcity let say 10 it creates an Object[10] in the background. >In case we leave it as new ArrayList<>() then creates an empty object array private static final
