# Java: Check whether three given lengths of three sides form a right triangle

## Java Basic: Exercise-213 with Solution

Write a Java program to check whether three given lengths (integers) of three sides form a right triangle. Print "Yes" if the given sides form a right triangle otherwise print "No".

Input:

Integers separated by a single space. 1 ≤ length of the side ≤ 1,000

Sample Solution:

Java Code:

``````import java.util.Arrays;
import java.util.Comparator;
import java.util.Scanner;

class Main {
// Creating a Scanner object for user input
Scanner sc = new Scanner(System.in);

// Method to execute the main functionality
public void run() {
// Prompting the user to input three integers (sides of a triangle)
System.out.println("Input three integers(sides of a triangle)");

// Reading three integers and storing them in an array
int[] int_num = new int[]{
sc.nextInt(), sc.nextInt(), sc.nextInt()
};

// Sorting the array of integers in ascending order
Arrays.sort(int_num);

// Checking if the given sides form a right triangle
System.out.println("If the given sides form a right triangle?");
ln((int_num[2] * int_num[2] == int_num[0] * int_num[0] + int_num[1] * int_num[1]) ? "Yes" : "No");
}

// Main method to create an instance of the class and run the program
public static void main(String[] args) {
new Main().run();
}

// Method for printing without a newline
public static void pr(Object o) {
System.out.print(o);
}

// Method for printing with a newline
public static void ln(Object o) {
System.out.println(o);
}

// Method for printing an empty line
public static void ln() {
System.out.println();
}
}
```
```

Sample Output:

```Input three integers(sides of a triangle)
6 9 12
If the given sides form a right triangle?
No
```
