I would like to test my code and I want to know what can be failed the compilation of my code I this the problem is in the string character maybe some character is not for string this code calcul the BMI and I want to know what is the problem if they have in my code
import java.util.Scanner;
public class BMI {
static Scanner sc = new Scanner(System.in);
static String size;
static String weight;
static boolean valid;
static Double p=0.0;
static Double t=0.0;
public static boolean isValidDouble(String str) {
try {
str = str.replaceAll(",", ".");
Double.parseDouble(str);
} catch (Exception e) {
return false;
}
return true;
}
public static double writeWeight() {
do{
System.out.println("what is your weight?");
poids = sc.nextLine();
valid = isValidDouble(weight);
if(valid){
weight = weight.replaceAll(",", ".");
p = Double.parseDouble(weight);
if(p < 30){
System.out.println("mistake: weight is too low");
valid = false;
}
if(p > 129){
System.out.println("Erreur: weight is to much");
valid = false;
}
}else
System.out.println("mistake: the weight should be number");
}while(valid == false);
return p;
}
public static void main(String[] args) {
p = writeWeight();
do{
System.out.println("what is your size?");
taille = sc.nextLine();
valid = isValidDouble(size);
if(valid){
size = size.replaceAll(",", ".");
t = Double.parseDouble(size);
if (t > 100)
t = t/100;
if(t<0.3){
System.out.println("mistake: size is too low.");
valide = false;
}
if( t>2.10) {
System.out.println("mistake: size is too much");
valid = false;
}
}else
System.out.println("mistake: the size should be a number");
}while(valid == false);
double bmi = p / (t*t);
System.out.println("BMI is: "+bmi);
}
}
can you test my code or write a test who can validate my code
