Two sorted arrays can be merged so that a single resultant sorted array is obtained. An example of this is given as follows.Array 1 = 1 3 7 9 10 Array 2 = 2 5 8 Merged array = 1 2 3 5 7 8 9 10A program that demonstrates this is given as follows.Example Live Demopublic class Example {    public static void main (String[] args) {       int[] arr1 = {11, 34, 66, 75};       int n1 = arr1.length;       int[] arr2 = {1, 5, 19, 50, 89, 100};       int ...

The order of the words in a string can be reversed and the string displayed with the words in reverse order. An example of this is given as follows.String = I love mangoes Reversed string = mangoes love IA program that demonstrates this is given as follows.Example Live Demoimport java.util.regex.Pattern; public class Example {    public static void main(String[] args) {       String str = "the sky is blue";       Pattern p = Pattern.compile("\s");       System.out.println("The original string is: " + str);       String[] temp = p.split(str);       String rev = ...

The Body Mass Index is the body mass in kilogram divided by the square of body height in meters. This is expressed as kg/m^2.A Java program that calculates the Body Mass Index (BMI) is given as follows.Exampleimport java.util.Scanner; public class Example {    public static void main(String args[]) {       Scanner sc = new Scanner(System.in);       System.out.print("Input weight in kilogram: ");       double weight = sc.nextDouble();       System.out.print("Input height in meters: ");       double height = sc.nextDouble();       double BMI = weight / (height * height);     ...

Suppose you are given two strings, your task is to write a Java program that checks whether the second string is the sub-string of the first one. String in Java is an immutable sequence of characters and sub-string is its small portion. Example Scenario: − Input 1: str = "The sunset is beautiful"; Input 2: sub_str = "sunset"; Output: res = found!! Using Iteration In this approach, the idea is to use a nested for loop and an if block. The outer for loop will iterate over the characters of the main string. For each starting position i, ...

To check whether the entered value is ASCII 7-bit printable, check whether the characters ASCII value is greater than equal to 32 and less than 127 or not. These are the control characters.Here, we have a character.char one = '^';Now, we have checked a condition with if-else for printable characters.if (c >= 32 && c < 127) {    System.out.println("Given value is printable!"); } else {    System.out.println("Given value is not printable!"); }Example Live Demopublic class Demo {    public static void main(String []args) {       char c = '^';       System.out.println("Given value = "+c);     ...

To check whether the entered value is ASCII 7-bit numeric, check the character from ‘0’ to ‘9’.Here, we have a numeric character.char one = '9';Now, we have checked a condition with if-else for numeric character from ‘0’ to ‘9’if (c >= '0' && c = '0' && c = '0' && c = '0' && c

To check whether the entered value is ASCII 7-bit numeric and character (alphanumeric), check the characters ASCII value for −A to Z Or a to z Or 0 to 9Here, we have the following value −char one = '5';Now, we have checked some conditions with if-else for ASCII 7-bit numeric and character.if ((one >= 'A' && one = 'a' && one = '0' && one = 'A' && one = 'a' && one = '0' && one = 'A' && one = 'a' && one = '0' && one

In this article, we will learn to subtract the week from the current date using Java. This is useful when you need to manipulate dates, such as calculating dates from previous weeks for scheduling or tracking purposes. We'll use two approaches: using the Calendar class and the LocalDate class, showcasing how to easily adjust dates. Problem Statement Write a program in Java to subtract a specified number of weeks from the current date and display the updated date − Input Run the program Output Current Date = Mon Nov 04 09:41:18 IST 2024 Updated Date = Mon Oct 21 09:41:18 ...

All distinct elements of an array are printed i.e. all the elements in the array are printed only once and duplicate elements are not printed. An example of this is given as follows.Array = 1 5 9 1 4 9 6 5 9 7 Distinct elements of above array = 1 5 9 4 6 7A program that demonstrates this is given as follows.Example Live Demopublic class Example {    public static void main (String[] args) {       int arr[] = {1, 5, 9, 1, 4, 9, 6, 5, 9, 7};       int n = arr.length;   ...

The array is cyclically rotated clockwise by one. This means that each of the array elements are displayed to the right by one and the last element ends up as the first element. An example of this is given as follows.Original array = 1 2 3 4 5 6 7 8 9 10 Rotated array = 10 1 2 3 4 5 6 7 8 9A program that demonstrates this is given as follows.Example Live Demopublic class Example {    public static void main(String[] args) {       int[] arr = {1, 2, 3, 4, 5, 6, 7, 8, 9, ...
