s1 = Integer.parseInt(input);

input = JOptionPane.showInputDialog("Enter s2");
s2 = Integer.parseInt(input);

input = JOptionPane.showInputDialog("Enter s2");
s3 = Integer.parseInt(input);

if((s1+s2)>s3 && (s1+s3)>s2 && (s2+s3)>s1)
{
int s=(s1+s2+s3)/2;
double area=Math.sqrt(s*(s-s1)*(s-s2)*(s-s3));
JOptionPane.showMessageDialog(null,"Area of triangle is " + area);
}
else
JOptionPane.showMessageDialog(null,"Triangle is not valid");
}
}
