Area of a triangle is half the product of its base and height. Therefore, to calculate the area of a triangle.Get the height of the triangle form the user.Get the base of the triangle form the user. Calculate their product and divide the result with 2.Print the final result.Exampleimport java.util.Scanner; public class AreaOfTriangle {    public static void main(String args[]){       int height, base, area;       Scanner sc = new Scanner(System.in);       System.out.println("Enter the height of the triangle ::");       height = sc.nextInt();       System.out.println("Enter the base of the triangle ::"); ...

Area of a rectangle is the product of its length and breadth. Therefore, to calculate the area of a rectangleGet the length of the rectangle form the user.Get the breadth of the rectangle form the user.Calculate their product.Print the product.ExampleBelow is an example to find the area of a rectangle in Java using Scanner class.import java.util.Scanner; public class AreaOfRectangle {    public static void main(String args[]){       int length, breadth, area;       Scanner sc = new Scanner(System.in);       System.out.println("Enter the length of the rectangle ::");       length = sc.nextInt();       ...

Given a square whose length of all its sides are l, write a Java program to find its area. A square is a rectangle whose length and breadth are same. Therefore, area of this type of rectangle is the square of its length. To calculate the area of square in Java, you simply need to multiply the given length of square with the length itself and store the result in another variable. Java Program to Find The Area of a Square A Java program that illustrates how to find the area of the square is shown below − public class ... Read More

Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function.Following is an example to find palindrome of a given number using recursive function.Examplepublic class PalindromeRecursion {    public static boolean isPalindrome(String str){       if(str.length() == 0 ||str.length()==1){          return true;       }       if(str.charAt(0) == str.charAt(str.length()-1)){          return isPalindrome(str.substring(1, str.length()-1));       }       return false; ...

To find the sum of elements of an array.create an empty variable. (sum)Initialize it with 0 in a loop.Traverse through each element (or get each element from the user) add each element to sum.Print sum.Exampleimport java.util.Arrays; import java.util.Scanner; public class SumOfElementsOfAnArray {    public static void main(String args[]){       System.out.println("Enter the required size of the array :: ");       Scanner s = new Scanner(System.in);       int size = s.nextInt();       int myArray[] = new int [size];       int sum = 0;       System.out.println("Enter the elements of the array one by one ");       for(int i=0; i
