January 8, 2024 - The ArrayUtils class has the subarray() method, which allows us to get a subarray quickly:

July 21, 2026 - The sorting algorithm is a parallel sort-merge that breaks the array into sub-arrays that are themselves sorted and then merged. When the sub-array length reaches a minimum granularity, the sub-array is sorted using the appropriate Arrays.sort method. If the length of the specified array is less than the minimum granularity, then it is sorted using the appropriate Arrays.sort method.

A subarray of an -element array is an array composed from a contiguous block of the original array's elements. For example, if , then the subarrays are , , , , , and .

May 6, 2022 - One of Java’s most convenient features is the length attribute associated with each array. Because of this feature, it isn’t necessary to pass both the array and its length to a method (as it is in some other languages). However, it leads to people creating methods with inflexible signatures. The subarray ...

The array [1,2,3,4,5] is a result of applying the subarray function, because the end index value would get changed to the array length.

class solution { // Recursive function to print all possible subarrays // for given array static void printSubArrays(int []arr, int start, int end) { // Stop if we have reached the end of the array if (end == arr.length) return; // Increment the end point and start from 0 else if (start > end) printSubArrays(arr, 0, end + 1); // Print the subarray and increment the starting point else { System.out.print("["); for (int i = start; i < end; i++){ System.out.print(arr[i]+", "); } System.out.println(arr[end]+"]"); printSubArrays(arr, start + 1, end); } return; } public static void main(String args[]) { int []arr = {1, 2, 3}; printSubArrays(arr, 0, 0); } }

July 24, 2025 - A subarray is a contiguous part of array, i.e., Subarray is an array that is inside another array.

February 7, 2025 - #include <stdio.h> //Prints all subarrays in arr[0..n-1] void subArray(int arr[], int n) { // Pick starting point for (int i = 0; i < n; i++) { // Pick ending point for (int j = i; j < n; j++) { // Print subarray between current starting and ending points for (int k = i; k <= j; k++) { printf("%d ", arr[k]); } printf("\n"); } } } int main() { int arr[] = {1, 2, 3, 4}; int n = sizeof(arr) / sizeof(arr[0]); printf("All Non-empty Subarrays:\n"); subArray(arr, n); return 0; } ... import java.util.ArrayList; public class GfG { //Prints all subarrays in arr[0..n-1] static void subArray(ArrayList<Int

February 22, 2023 - String[] names = {"Alex", "Brian", "Charles", "David"}; String[] partialNames = ArrayUtils.subarray(names, 0, 2); // [Alex, Brian] The following Java example demonstrates to create an ArrayList from a subarray.

In this approach, we find all the subarrays but using recursion. import java.io.*; public class Main { //main method public static void main(String[] args) { // The array elements int arr[] = { 10, 2, 3}; System.out.println("The subarrays are-"); // Calling the recursive function printSubArrays(arr, 0, 0); } // Recursive FUnction to Find all the subarrays static void printSubArrays(int[] arr, int head, int tail) { // Exits the function if we have reached the end if (tail == arr.length) return; // Increases the first index and calls itself else if (head > tail) printSubArrays(arr, 0, tail + 1); // Print the subarray and then increases the first element index else { for (int i = head; i < tail; i++) System.out.print(arr[i] + " "); System.out.println(arr[tail]); printSubArrays(arr, head + 1, tail); } return; } }

April 18, 2025 - A subarray is a part of an array, a substring is a part of a string etc. They are all the very same thing, but for different data structures. Do you actually want to know when and where to use an arrays vs.

March 25, 2019 - Is there anything similar to subvec for Java Arrays? Crrently I’m using take and nthnext (Update: This is just an example on how I’m using take and nthnext): (defn sub-seq [from to coll] ;; Update: Name was subseq before, but core already has that name. (let [size (- to from)] (take size (nthnext coll from)))) But I feel there should be an already core function for this or something.

March 31, 2023 - In Julia, slicing operations like x[1:10] create a copy by default. However, copying data is not always the fastest option; in some cases, using a "view" into the parent array is more effici...
