Write the method called printTriangleType referred to in Sel

Write the method called printTriangleType referred to in Self-Check Problem 22. This method accepts three integer arguments representing the lengths of the sides of a triangle and prints the type of triangle that these sides form. Here are some sample calls to printTriangleType:

The output produced by these calls should be

Your method should throw an IllegalArgumentException if passed invalid values, such as ones where one side’s length is longer than the sum of the other two, which is impossible in a triangle. For example, the call of printTriangleType(2, 18, 2); should throw an exception.

Solution

Hi, Please find my code.Pleas elet me know in case of any issue.

public class PrintTriangle {

   public static void printTriangleType(int s1, int s2, int s3){

       // checking for invalid triangle side

       if((s1 > s2+s3) || (s2 > s1+s3) || (s3 > s2+s1)){

           throw new IllegalArgumentException(\"Triangle is not possible\");

       }

       // checking for right angle triangle

       if((s1 == Math.sqrt(s2*s2 + s3*s3)) || (s2 == Math.sqrt(s1*s1 + s3*s3)) || (s3 == Math.sqrt(s2*s2 + s1*s1))){

           System.out.print(\"rightangle ,\");

       }

       // checking for equilateral triangle

       if((s1 == s2) && (s2 ==s3)){

           System.out.println(\"equilateral\");

       }

       else if((s1==s2) || (s2==s3) || (s1==s3)){

           System.out.println(\"isosceles\");

       }

       else{

           System.out.println(\"scalene\");

       }

   }

   public static void main(String[] args) {

       printTriangleType(5, 7, 7);

       printTriangleType(6, 6, 6);

       printTriangleType(5, 7, 8);

       try{

           printTriangleType(2, 18, 2);

       }catch(IllegalArgumentException e){

           System.out.println(e.getMessage());

       }

   }

}

/*

Sample run:

isosceles

equilateral

scalene

Triangle is not possible
