Java Program to Calculate Distance between Two Points

You have given two points with coordinates (x1, y1) and (x2, y2). Write a Java program to find the distance between these two points.

We can find the distance between two points using the distance formula.

Distance = sqrt((x2-x1) ^ 2 + (y2-y1) ^ 2)

Example 1:
Input: (x1,y1) = (3,4)
           (x2, y2) = (7, 7)
Output: 5

Java Program: 

// Java program to find distance between two points

import java.util.Scanner;

public class Main {
	
	public static void main(String[] args) { 
		Scanner sc = new Scanner(System.in);
		
		int x1, y1, x2, y2;
		
		// take inputs
		System.out.println("Enter x1: ");
		x1 = sc.nextInt();
		System.out.println("Enter y1: ");
		y1 = sc.nextInt();
		
		System.out.println("Enter x2: ");
		x2 = sc.nextInt();
		System.out.println("Enter y2: ");
		y2 = sc.nextInt();
		
		// find distance using distance formula
		double distance = Math.sqrt(((x2-x1) * (x2-x1)) + ((y2-y1) * (y2-y1)));
		System.out.println("Distance between (" + x1 + "," + y1 + ") and (" + x2 + "," + y2 + ") => " + distance);
		
		sc.close();
	}

}

Output: 

Enter x1: 
3
Enter y1: 
4
Enter x2: 
7
Enter y2: 
7
Distance between (3,4) and (7,7) => 5.0

LeetCode - Bulb Switcher Solution - The Coding Shala

Image
Home >> LeetCode >> Bulb Switcher LeetCode - Bulb Switcher Solution In this post, we will discuss LeetCode's Bulb Switcher Problem and its solution in Java. There are n bulbs that are initially off. You first turn on all the bulbs. Then, you turn off every second bulb. On the third round, you toggle every third bulb (turning on if it's off or turning off if it's on). For the i-th round, you toggle every i bulb. For the n-th round, you only toggle the last bulb. Find how many bulbs are on after n rounds. Example: Input: 3 Output: 1 Explanation: At first, the three bulbs are [off, off, off]. After the first round, the three bulbs are [on, on, on]. After the second round, the three bulbs are [on, off, on]. After the third round, the three bulbs are [on, off, off].  So you should return 1 because there is only one bulb is on. Practice this problem on LeetCode(Click Here). Java Solution of Bulb Switcher Problem Let's

Sorting the Sentence LeetCode Solution - The Coding Shala

Home >> LeetCode >> Sorting the Sentence  In this post, we will learn how to solve LeetCode's Sorting the Sentence Problem and will implement its solution in Java. Sorting the Sentence Problem A sentence is a list of words that are separated by a single space with no leading or trailing spaces. Each word consists of lowercase and uppercase English letters. A sentence can be shuffled by appending the 1-indexed word position to each word then rearranging the words in the sentence. For example, the sentence "This is a sentence" can be shuffled as "sentence4 a3 is2 This1" or "is2 sentence4 This1 a3". Given a shuffled sentence s containing no more than 9 words, reconstruct and return the original sentence. Example 1: Input: s = "is2 sentence4 This1 a3" Output: "This is a sentence" Explanation: Sort the words in s to their original positions "This1 is2 a3 sentence4", then remove the numbers. Example 2: Input:

Java Method Overloading - The Coding Shala

Image
Home >> Learn Java >> Java Method Overloading Java Method Overloading Java class can have more than one method with the same name but different in parameters, known as Method Overloading. Question: What is the use of method overloading? Answer:  Suppose we want to perform some operation like an addition but addition can be performed between two numbers, three numbers or two floats or more. So instead of using different methods, we use the same name of the method with different parameters. This can increase the readability of the program. Method overloading can be achieved by changing numbers of arguments or by changing the data types. Example of Method Overloading in Java The following example explains Method Overloading: //Method Overloading example class Addition { public int add ( int a , int b ){ return a + b ; } public int add ( int a , int b , int c ){ return a + b + c ; }
