Java Program to Check Whether It Is Possible to Draw a Triangle with Given Sides

For existence of a triangle there is a condition. The condition is that the sum of the lengths of any two sides of a triangle must be greater than or equal to the length of the third side. If the sum of the lengths of any two sides of a triangle is equal to the length of the third side, it forms a triangle with zero area. The vertices are collinear in that case. Still we can say that the triangle exists. So, here we will see a java program to check whether a triangle exists or not with given sides. The program is as follows:

import java.util.Scanner;

public class TriangleSide {
public static void main(String[] arg)
    {
    
    Scanner sc=new Scanner(System.in);
    System.out.println("Enter the sides of triangle");
    int a=sc.nextInt(),b=sc.nextInt(),c=sc.nextInt();
    if(a+b>=c&&b+c>=a&&c+a>=b)
        System.out.println("possible");
    else
        System.out.println("impossible");
    }
}
