This resource features 79 Java Array Exercises, each complete with solutions and detailed explanations.

Java Array : An array is a group of similar typed variables that are referred to by a common name. Arrays of any type can be created and may have one or more dimensions.

Test Data: array1 = 50, -20, 0, 30, 40, 60, 12 array2 = 45, 20, 10, 20, 30, 50, 11 Sample Output: ... Write a Java program to create an array of length 2 from two integer arrays with three elements. The newly created array will contain the first and last elements from the two arrays.

The newly created array will contain the first and last elements from the two arrays. ... import java.util.Arrays; public class Exercise77 { public static void main(String[] args) { // Define two integer arrays (array1 and array2) int[] array1 = {50, -20, 0}; int[] array2 = {5, -50, 10}; // Print the elements of array1 System.out.println("Array1: " + Arrays.toString(array1)); // Print the elements of array2 System.out.println("Array2: " + Arrays.toString(array2)); // Create a new array, array_new, with elements from array1 and array2 int[] array_new = {array1[0], array2[2]}; // Print the elements of the new array, array_new System.out.println("New Array: " + Arrays.toString(array_new)); } }

Java.util.ArrayList Class: ArrayList Class represents a dynamically sized, index-based collection of objects. Implements all optional list operations, and permits all elements, including null.

Java Collection, ArrayList Exercises and solution: Write a Java program to create an array list, add some colors (strings) and print out the collection.

Write a Java program to form a character array from a string and then replace every consonant with the next alphabet letter.

Java programming exercises and solution: Write a Java program to create a two-dimensional array (m x m) A[][] such that A[i][j] is false if I and j are prime otherwise A[i][j] becomes true.

Learn how to create a Java class with a parameterized constructor that initializes an array of strings and a string variable.

public class Main { static int [] nums; public static void main(String[] args) { nums = new int[]{3,2,4,5,6,6,7,8,9,9,0,9}; int result = Linear_Search(nums, 6); if(result == -1) { System.out.print("Not present in the array!"); } else System.out.print("Number found at index "+result); } private static int Linear_Search(int [] nums,int search) { for(int i=0;i<nums.length;i++) { if(nums[i]==search) { return i; } } return -1; } } ... Write a Java program to implement linear search on a linked list without using index-based access.

Java provides an ArrayList class which can be used to create containers that store lists of objects. ArrayList can be considered as a growable array. It gives you fast iteration and fast random access.

Write a Java program to extract the first half of an ArrayList and then merge it with the second half reversed.
