Here is an example of how System.arraycopy() can be used to remove an element from an array in Java: public class Main { public static void main(String[] args) { int[] arr = {1, 2, 3, 4, 5}; int removeIndex = 2; int[] newArr = new int[arr.length - 1]; System.array...
In this article, we will learn how to find the largest and smallest number in an array in Java. Finding the largest and smallest values is a common task in programming. We will explain this in simple steps to make it easy to understand. What is an Array in Java? An array is ...
Java program to find the maximum element of an array using recursion. classRecursiveMax{publicstaticvoidmain(String[]args){int[]arr={10,5,7,9,15,6,11,8,12,2,3};intmax=recursiveMax(arr, arr.length);System.out.println("Maximum element: "+max);}staticintrecursiveMax(int[]arr,intlength...
In this short tutorial, we’re going to see how to find the maximum and the minimum values in an array, using Java 8’s Stream API. We’ll start by finding the minimum in an array of integers, and then we’ll find the maximum in an array of objects. 2. Understanding the Algorithm...
Implement a method that finds the index of the K-th element equal to the minimum in an array of ints. If no such element can be found, return -1. The
In this tutorial, we’ll implement different solutions to the problem offinding theklargest elementsin an array with Java. To describe time complexity we`ll be usingBig-Onotation. 2. Brute-Force Solution The brute-force solution to this problem is toiterate through the given arrayktimes.In ea...

Since the array is increasing first & then decreasing so the maximum element would be the last one in the increasing series & the first one in the decreasing series. SO we can ignore the increasing part and check if the next element is decreasing or not. As soon as we fin...
I am trying to find the max value of id:x in an associative array that is located in a text file located in the same folder as my script. I found 2 working examples, one finds the max value and the other reads the array from a text file. I am trying to put them together, but...
