easy📝 Syntax Q3 of 15

Java - Arrays

Aint[] arr = new int[3]{1, 2, 3};

Bint arr[] = new int{1, 2, 3};

Cint arr[] = {1, 2, 3};

Dint[] arr = {1; 2; 3};

Step-by-Step Solution

Solution:

Step 1: Understand array initialization syntax
In Java, you can initialize an array with values using curly braces without specifying size explicitly.
Step 2: Check each option
int arr[] = {1, 2, 3}; uses correct syntax: int arr[] = {1, 2, 3}; int[] arr = new int[3]{1, 2, 3}; incorrectly combines size and initializer. int arr[] = new int{1, 2, 3}; misses brackets after new int. int[] arr = {1; 2; 3}; uses semicolons instead of commas.
Final Answer:
int arr[] = {1, 2, 3}; -> Option C
Quick Check:
Array initialization with values = int arr[] = {1, 2, 3}; [OK]

Quick Trick: Use commas inside braces to list array values [OK]
