{String input;
double weight,height,bmi;
String output;
Scanner keyboard = new Scanner(System.in);
//input

input= JOptionPane.showInputDialog(null,"Enter yourweight: ");
weight=Double.parseDouble(input);
input = JOptionPane.showInputDialog(null,"Enter yourheight: ");
height=Double.parseDouble(input);
//calculations
bmi =(weight * 703) / (height * height);



if(bmi < 18.5)
{
output = "You areunderweight.";
}
else if(bmi >25)
{
output = "You areoverweight";
