Question

Java, I get a index out of bounds exception with this method, can you spot where the method goes out of bounds from this code?

public void showEarliestAttack(){
    String earliestAttack;

    for (int i = 0; i < attackArray.size(); i++) {
        earliestAttack= attackArray.get(i).toString();
       if(attackArray.get(i+1).getDate().compareTo(attackArray.get(i).getDate())<0){
           earliestAttack = attackArray.get(i+1).toString();
       }
        System.out.println(earliestAttack);
    }




}

Answer 1

public void showEarliestAttack() {
    String earliestAttack;

    for (int i = 0; i < attackArray.size() - 1; i++) {  // only iterate until size-1. because you are accessing i+1 element in the loop body
        earliestAttack = attackArray.get(i).toString();
        if (attackArray.get(i + 1).getDate().compareTo(attackArray.get(i).getDate()) < 0) {
            earliestAttack = attackArray.get(i + 1).toString();
        }
        System.out.println(earliestAttack);
    }
