Java Program to Find the Area of Circle - The Coding Shala

Home >> Java Programs >> Area of Circle

 In this post, we will learn how to write a Java Program to Find the Area of Circle.

Java Program to Find the Area of Circle

The radius of the circle is given, find the area of the circle using the Java program.

Area of Circle = Pi * (radius * radius)

Example 1:
Input: radius = 3
Output: Area = 28.274333882308138

Java Program: 

// Java program to Find Area of Circle

import java.util.Scanner;

public class Main {
	
	public static void main(String[] args) { 
		Scanner sc = new Scanner(System.in);
		
		// take radius input
		System.out.println("Enter the radius of circle");
		double radius = sc.nextDouble();
		
		// calculate the area
		// area = Pi * (radius * radius)
		double area = Math.PI * (radius * radius);
		System.out.println("Area of Circle is: " + area);
		
		sc.close();
	}
}

Output: 

Enter the radius of circle
3
Area of Circle is: 28.274333882308138

Java Program to Convert Binary to Decimal - The Coding Shala

Home >> Java Programs >> Convert Binary to Decimal  Hey there, welcome back to another post. In this post, we will learn how to convert Binary to Decimal in Java. Java Program to Convert Binary to Decimal You have given a binary number, convert it to a decimal number. Example:  Input: 101 Output: 5 Input: 111 Output: 7 Binary to Decimal Conversion in Java Approach We will the below formula to convert binary to decimal: decimal number = (2^0) * (rightmost digit) + (2^1) * (second rightmost digit) + ...  for example:  binary number = 110 decimal number = 2^0 * 0 + 2^1 * 1 + 2^2 * 1 = 1 * 0 + 2 * 1 + 4 * 1 = 0 + 2 + 4 = 6 Java Program:  import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void printDecimal( int num) { int decimal = 0; int twos = 1; // 2^0 = 1 initial value while (num > 0) { int temp = num

N-th Tribonacci Number Solution - The Coding Shala

Home >> Programming >> N-th Tribonacci Number  Hey there, welcome back to another post. In this post, we will learn how to solve the N-th Tribonacci Number problem and will implement its solution in Java. N-th Tribonacci Number Problem Statement The Tribonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn+3 = Tn + Tn+1 + Tn+2 for n >= 0. Given n, return the value of Tn.  Example 1:  Input: n = 4 Output: 4 Explanation: T_3 = 0 + 1 + 1 = 2 T_4 = 1 + 1 + 2 = 4 N-th Tribonacci Number Java Solution using Bottom-Up DP This problem is similar to the Fibonacci series. We can solve it using the Bottom-Up approach of dynamic programming. Time Complexity: O(n) Space Complexity: O(n) The space complexity can be reduced to O(1) by using variables to store the previous three values instead of using an array. Java Program:  class Solution { public int tribonacci( int n) { if (n == 0) return 0; if (n == 1 || n == 2

Introduction to Kotlin Programming Language for Backend Development - The Coding Shala

Home >> Learn Kotlin >> Kotlin Introduction Are you looking for a powerful and reliable programming language for backend development? Look no further than Kotlin. Kotlin is a modern, statically typed programming language that has gained a lot of popularity in recent years. In this blog post, we'll take a look at what Kotlin is and why it's a great choice for backend development. What is Kotlin? Kotlin is a statically typed, cross-platform, general-purpose programming language that was developed by JetBrains in 2011. It is designed to be more concise, expressive, and safe than Java, the most widely used programming language for Android development. Kotlin can be compiled to run on the Java Virtual Machine (JVM), JavaScript, and native platforms, making it a versatile language for different types of applications. Why use Kotlin for backend development? Kotlin has several features that make it a suitable language for backend development, such as: Concisenes

Java Program to Reverse a String using Stack - The Coding Shala

Home >> Java Programs >> Reverse a String using Stack  Hey there, welcome back to another post. In this post, we will learn how to reverse a string using a stack in Java. Java Program to Reverse a String using Stack As we know,  Stack data structure follows last in the first out (LIFO), so by using stack we can reverse a given string. For example:  Input: hello output: olleh After storing into stack Stack -> o l l e h Now print stack -> olleh Java Program:  import java.util.Scanner; import java.util.Stack; /** * https://www.thecodingshala.com/ */ public class Main { public static String doReverse(String str) { Stack<Character> stack = new Stack<>(); // push all characters into stack for ( int i = 0; i < str.length(); i++) { stack.push(str.charAt(i)); } // pop characters from stack and build string Stri
