Question

How to write a Java program that after prompting the user to enter the lengths of sides (3) of a triangle, it prints:

"Enter the lengths of the sides of triangle 1: 6 6 6"

"A triangle with sides of 6,6,6 is equilateral."

Answer 1

import java.util.Scanner;
public class TypeOfTriagle {
  public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    System.out.print("Enter the lengths of the sides of triangle 1: ");
    int a = scanner.nextInt();
    int b = scanner.nextInt();
    int c = scanner.nextInt();

    String result;

    if (a == b && b == c)
      result = "equilateral";
    else if (a == b || b == c)
      result = "isosceles";
    else
      result = "scalene";

    System.out.println("A triangle with sides of 6,6,6 is "+result+".");
  }
}

Output:

Enter the lengths of the sides of triangle 1: 6 6 6
A triangle with sides of 6,6,6 is equilateral.
