Question

write a program in Java language to enter the three angles of a triangle and check for the validity of the triangle....plz answer the question​

Answer 1

CODE

import java.util.*;

class triangle_validity

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter the three angles of triangle");

int a=sc.nextInt();

int b=sc.nextInt();

int c=sc.nextInt();

if(a+b+c==180&&a!=0&&b!=0&&c!=0)

{

System.out.println("Triangle valid");

}

else

{

System.out.println("Triangle invalid");

}

}

}//the End

NOTE :

Triangle property is that all angles are added to get 180 degrees . Any angle cannot be 0 degrees .

Answer 2

Hey there!

The coding is as follows:

import java.io.*;

class Validity_of_triangle   //Declaration of class

{

public static void main(String args[]) throws IOException

{

//Making Input Stream Reader object

InputStreamReader ir = new InputStreamReader(System.in);    

BufferedReader br= new BufferedReader(ir);

System.out.println("Enter the three angles of triangle");

int a=Integer.parseInt(br.readLine());

int b=Integer.parseInt(br.readLine());

int c=Integer.parseInt(br.readLine());

// using AND logical operator

if(a+b+c==180&&a!=0&&b!=0&&c!=0)

{

System.out.println("Triangle is valid");

}

else

{

System.out.println("Triangle is invalid");

}

}

}       //End of the program
