How to copy elements of one array to another array in Java - Arrays.copyOf and Arrays.copyOfRange Example

There are multiple ways to copy elements from one array in Java e.g. you can manually copy elements by using a loop, create a clone of the array, use Arrays.copyOf() method or System.arrayCopy() to start copying elements from one array to another in Java. Even though both allow you to copy elements from source to destination array, the Arrays.copyOf() is much easier to use as it takes the just original array and the length of the new array. But, this means you cannot copy subarray using this method because you are not specifying to and from an index, but don't worry there is another method in the java.util.Arrays class to copy elements from one index to other in Java, the Arrays.copyOfRange() method. Both methods are overloaded to copy different types of array.
