Can anyone identify the error?

Question

public class Program
{
static int sumb(int a){
int n=0;
while(a!=0){
n=n+a;
}
return n;
}
public static void main(String[] args) {
int numb=123,a;
while(numb!=0){
a=numb%10;
int suma=sumb(a);
numb=numb/10;
}
System.out.println(suma);
}
}

Answer 1

Ajoh Pv You declared suma inside the loop which will be consider as local variable.
int suma = sumb(a); //wrong declaration of suma

Answer 2

Ajoh Pv Your second loop in method sumb is going till infinity that is why you get that error. Why it is going till infinite because a is always greater than 0 in 2nd loop.

Answer 3

Ajoh Pv
Change
int suma = sumb(a)
To
suma = suma + sumb(a);
And
while (a != 0) to if(a != 0)

Answer 4

Ajoh Pv Yes while loop will Check till condition is satisfying but what you want to do and why you made 2nd loop?
