In this article, we will learn how to write a Java program to calculate the total number of vowels in each string in an array. This problem is a great example of practicing working with arrays and string manipulation in Java. Problem statement: We are given an array of strings, and the task is to …
Problem statement: Write a Java program to identify and print all palindrome strings in a given Array of strings. What is a Palindrome? A word is a palindrome if it reads the same forward and backward, e.g., “madam” or “racecar.” Find palindrome in string Array Java Program This program identifies and lists all palindrome words …

Printing all negative elements in an array involves iterating through the array and checking if each element is less than 0. Negative numbers are then displayed as output. OUTPUT:Negative elements in the array:-5 -15 -25 Read Also: Print Odd/Even No. from an Array. | Sum of Two Arrays.
Removing odd numbers from an array involves iterating through the elements, identifying odd numbers, and creating a new array that excludes them. In this post, we will explore two examples of removing odd numbers from an array in Java: one using a traditional array approach and the other leveraging an ArrayList for dynamic resizing. Example-1: …
Separating even and odd elements into two arrays involves iterating through the original array, checking each element’s parity using the modulus operator (%), and adding it to the respective array. In this article, we will explore two practical approaches to separate even and odd numbers from an array into two distinct arrays using Java. This …

Counting even and odd numbers in an array involves iterating through each element and checking whether it is divisible by 2. Even numbers have a remainder of 0 when divided by 2, while odd numbers do not. Java Program to Count Even and Odd Numbers in an Array This Java program counts the number of …
Comparing two arrays in Java involves checking if they are equal in terms of size, order, and elements. You can use manual loops for element-by-element comparison, or depend on built-in methods like Arrays.equals() or Arrays.deepEquals() for multidimensional arrays. To determine if two arrays are equal, the following conditions must be checked: For multidimensional arrays, nested …
Counting repeated elements in a Java array involves identifying elements that appear more than once and tallying their occurrences. This can be achieved using nested loops, a HashMap, or other data structures for efficient tracking. 1. Count Repeated Elements in Array Using Nested Loops This program example iterates through the array and compares each element …
Removing an element from a Java array involves creating a new array, excluding the specified element, and shifting the remaining elements as arrays are of fixed size. Alternatively, you can use ArrayList for easier element removal due to its dynamic nature. Remove Element Using a New Array This program creates a smaller array, excluding the …
Ternary Search is a divide-and-conquer searching algorithm designed for sorted arrays. It works by dividing the search range into three equal parts and recursively narrowing down the range where the target element might be located. It is particularly useful for unimodal functions or when the search space is ordered and well-structured. How Ternary Search Works? …
