Question

Which of the following is not a correct way to initialize an array?

1) int[] arr = new int[5];
2) int[] arr = {1, 2, 3, 4, 5};
3) int[] arr = new int[]{1, 2, 3, 4, 5};
4) int[] arr = new int[5]{1, 2, 3, 4, 5};

Answer 1

The correct options for initializing an array in Java explained.

Step-by-step explanation:

The correct way to initialize an array in Java is:

1. int[] arr = new int[5];
2. int[] arr = {1, 2, 3, 4, 5};
3. int[] arr = new int[]{1, 2, 3, 4, 5};

The incorrect way to initialize an array is:

• int[] arr = new int[5]{1, 2, 3, 4, 5};

Option 4 is not valid because when using the new keyword to initialize an array, you cannot provide explicit values inside the square brackets.
