slice array java

   //index   0   1   2   3   4
int[] arr = {10, 20, 30, 40, 50};
Arrays.copyOfRange(arr, 0, 2);          // returns {10, 20}
Arrays.copyOfRange(arr, 1, 4);          // returns {20, 30, 40}
Arrays.copyOfRange(arr, 2, arr.length); // returns {30, 40, 50} (length = 5)

slicing array in java

import java.util.Arrays;
public class SlicingAnArray {
   public static void main(String args[]){
      int intArray[] = {12, 14, 58, 225, 56, 96 , 3, 45, 8 };
      intArray = Arrays.copyOfRange(intArray, 3, 7);
      System.out.println(Arrays.toString(intArray));
   }
}

java Array slicing

Arrays.copyOfRange(myArray, startIndex, endIndex);
This takes O(n)O(n)O(n) time and O(n)O(n)O(n) space, where nnn is the number of elements in the resulting array.
