java copy array

To copy an array in Java, you can use the System.arraycopy method, or you can create a new array and copy the elements from the original array using a loop.

Here is an example of how you can use the System.arraycopy method to copy an array in Java:

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

In this example, we have an int array called original that contains some values. We create a new int array called copy with the same length as the original array, and use the System.arraycopy method to copy the elements from the original array to the copy array.

Here is an example of how you can use a loop to copy an array in Java:

int[] original = {1, 2, 3, 4, 5};
int[] copy = new int[original.length];
for (int i = 0; i < original.length; i++) {
    copy[i] = original[i];
}

In this example, we have an int array called original that contains some values. We create a new int array called copy with the same length as the original array, and use a loop to iterate over the original array. For each element, we copy the value to the corresponding element in the copy array.
