#Java Tip — Day 5: Clone Arrays the Smart Way
Instead of looping manually to copy arrays, use the built-in methods for clean and efficient code 👇
int[] nums = {1, 2, 3, 4, 5};
// Clone using built-in methods
int[] copy1 = nums.clone();
int[] copy2 = Arrays.copyOf(nums, nums.length);
int[] copy3 = Arrays.copyOfRange(nums, 1, 4); // copies 2,3,4
✅ Why this matters:
Faster and less error-prone than manual copying
clone() keeps the same type
copyOfRange() gives you flexibility to take slices
