Fix NullPointerException by properly initializing the List.
The current code will throw a NullPointerException when trying to add elements because the List is initialized to null. Additionally, the iteration would also fail for the same reason.
Apply this diff to properly initialize the List:
- List<String> names = null;
+ List<String> names = new ArrayList<>();Also, consider using the enhanced for loop for better readability:
- for (int i = 0; i < names.size(); i++) {
- System.out.println(names.get(i));
+ for (String name : names) {
+ System.out.println(name);📝 Committable suggestion
‼️ IMPORTANT
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.
| List<String> names = null; | |
| names.add("Alice"); | |
| names.add("Bob"); | |
| names.add("Charlie"); | |
| for (int i = 0; i < names.size(); i++) { | |
| System.out.println(names.get(i)); | |
| } | |
| List<String> names = new ArrayList<>(); | |
| names.add("Alice"); | |
| names.add("Bob"); | |
| names.add("Charlie"); | |
| for (String name : names) { | |
| System.out.println(name); | |
