write a program to input 3 numbers of a triangle and check whether a triangle is possible or not if possible then check whether it is an acute angle triangle right angle triangle or an acute angle triangle otherwise display triangle not possible

import java.util.Scanner;
public class Triangle
{
public static void main(String args[])
{
Scanner in = new Scanner(System.in);
System.out.print("Enter first angle: ");
int a1 = in.nextInt();
System.out.print("Enter second angle: ");
int a2 = in.nextInt();
System.out.print("Enter third angle: ");
int a3 = in.nextInt();
int angleSum = a1 + a2 + a3;
if (angleSum == 180 && a1 > 0 && a2 > 0 && a3 > 0)
{
if (a1 < 90 && a2 < 90 && a3 < 90)
{
System.out.println("Acute-angled Triangle");
}
else if (a1 == 90 || a2 == 90 || a3 == 90)
{
System.out.println("Right-angled Triangle");
}
else
{
System.out.println("Obtuse-angled Triangle");
}
}
else
{
System.out.println("Triangle not possible");
}
}
