Question

Prompt for three (3) nonzero integers and determine and print if they could be sides of a right-angled triangle (Hint: any two sides are equal)

Answer 1

import java.util.Scanner;

public class printTriangle {

 public static String drawTriangle(int n){

  String s = "";

  for (int i = 1; i <= n; i++){

   for (int j = 1; j <= i; j++)

    s += "*";

   s += "\n";

   }

  return s;

 }

public static void main(String[] args) {

System.out.println("Please input 1st side:");

String first = (new Scanner(System.in)).nextLine();

System.out.println("Please input 2nd side:");

String second = (new Scanner(System.in)).nextLine();

System.out.println("Please input 3rd side:");

String third = (new Scanner(System.in)).nextLine();

int firstSide = Integer.valueOf(first);

int secondSide = Integer.valueOf(second);

int thirdSide = Integer.valueOf(third);

if(firstSide==secondSide && secondSide==thirdSide){

String output = "";

output += drawTriangle(firstSide);

System.out.println("Could be");

System.out.println(output);

}

else{

System.out.println("Could NOT be");

}

}

}

Answer 2

import java.util.Arrays;
import java.util.Scanner;

public class RightAngle {
public static void main(String[] args) {
System.out.println("Please input 1st side:");
String first = (new Scanner(System.in)).nextLine();

System.out.println("Please input 2nd side:");
String second = (new Scanner(System.in)).nextLine();

System.out.println("Please input 3rd side:");
String third = (new Scanner(System.in)).nextLine();

int firstSide = Integer.valueOf(first);
int secondSide = Integer.valueOf(second);
int thirdSide = Integer.valueOf(third);

int[] sideArr = { firstSide, secondSide, thirdSide };
Arrays.sort(sideArr);

if (sideArr[2] * sideArr[2] == sideArr[0] * sideArr[0] + sideArr[1] * sideArr[1]) {
System.out.println("Could be");
} else {
System.out.println("Could NOT be");
}
}
