Question

I have created an ArrayList of Object and it contains both Integer and String.

List<Object> arrayList = new ArrayList<>();

Using the below condition I have checked whether it is integer or not

if(arrayList.get(indexValue) instanceof Integer){
 // Here how convert the object into integer
}

But the problem is, how can I convert the object into integer ?

Thanks

You can explicitly cast it to Integer but dont need Java does does it for you.

if(arrayList.get(indexValue) instanceof Integer){
  Integer i = arrayList.get(indexValue);
}
