Missing upper bound check causes ArrayIndexOutOfBoundsException.
The method only validates against negative indices but doesn't check if pos exceeds the array bounds. When pos >= store.length (i.e., pos >= 4), line 8 will throw ArrayIndexOutOfBoundsException.
Apply this diff to add the missing upper bound validation:
public static void putData(int pos, int num) {
- if (pos < 0) {
+ if (pos < 0 || pos >= store.length) {
return;
}
store[pos] = num;

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In BadArray.java around lines 4 to 9, the method validates only negative indices
and misses an upper bound check, causing ArrayIndexOutOfBoundsException when pos
>= store.length; add a guard that checks if pos is greater than or equal to
store.length (e.g., if (pos >= store.length) return; or throw an appropriate
exception) before writing to store[pos] so out-of-range indices are handled
safely.

Array index out of bounds: attempting to access index 5 in array of size 4.
The call to putData(5, 100) will throw ArrayIndexOutOfBoundsException because store has size 4 (valid indices: 0-3), but the code attempts to write to index 5.
Apply this diff to use a valid index:
public static void main(String[] args) {
- putData(5, 100);
+ putData(3, 100);

In BadArray.java around lines 11 to 13, the call putData(5, 100) writes to index
5 while the underlying array has length 4 (valid indices 0–3), causing an
ArrayIndexOutOfBoundsException; change the call to use a valid index (for
example putData(3, 100)) or otherwise ensure the index is within bounds
(validate the index before calling or increase the array size) so the write does
not exceed the array length.
