Java Array Assignment Methods Explained

1. Iterate through the array in a loop and assign values one by one.

int[] arr = new int[5];
for (int i = 0; i < arr.length; i++) {
    arr[i] = i + 1;
}

1. Initialize using static initialization:

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

1. Assigning the same value using the Arrays.fill() method.

int[] arr = new int[5];
Arrays.fill(arr, 0);

1. Copy an array using the System.arraycopy() method.

int[] arr1 = {1, 2, 3, 4, 5};
int[] arr2 = new int[arr1.length];
System.arraycopy(arr1, 0, arr2, 0, arr1.length);
