Question
What would be the result of the following code snippet?int[] ages = {50, 40, 30, 20};Arrays.sort(ages);int[] agesOther = Arrays.copyOfRange(ages, ages.length - 2, ages.length);System.out.println(Arrays.toString(agesOther));[30, 20][40, 50][20, 30][50, 40]
Solution
The result of the code snippet would be [40, 50].
Here's the step by step explanation:
- An array named 'ages' is declared with the elements 50, 40, 30, 20.
- The array 'ages' is sorted using Arrays.sort() method. After sorting, the array 'ages' would look like this: [20, 30, 40, 50].
- A new array 'agesOther' is created by copying the last two elements of the sorted 'ages' array using Arrays.copyOfRange() method. The parameters for this method are the original array, the initial index, and the final index. In this case, it copies from 'ages.length - 2' (which is 2) to 'ages.length' (which is 4). So, it copies the elements at index 2 and 3 of the 'ages' array.
- The elements at index 2 and 3 of the 'ages' array are 40 and 50 respectively. So, the 'agesOther' array would be [40, 50].
- Finally, the 'agesOther' array is printed out using System.out.println() and Arrays.toString() methods. The output would be [40, 50].
