Question

*JAVA*

Assume we already have an ArrayList of Integers called list. Write code that will add 1 to each element of the list. For example, if the list originally contained 2, 4, -3, then it should contain 3, 5, -2 after the lines of code execute. Just write the necessary lines of code (not a whole method or program). Assume we already created the ArrayList and filled it with Integers.

Answer 1

int value;
for(int i = 0;i<list.size();i++){
    value = list.get(i);
    list.remove(0);
    list.add(i,value+1);
}
