In the following example, we are creating the subarrays from an array of different lengths. Notice if the new array length is greater than the original array then extra array places are filled with thedefault value of the data type. In given example, the default value ofStringtype isnullso...

Inside the method, an empty array (slicedArr) is created with a size equal to the difference between the end and start indices. Then, aforloop iterates through the elements, copying them from the original array to the sliced array. The sliced array is then returned. ...
