I have a problem in my behavior method. Because my while condition is not reading the value of 0 if i put it in the first place.

Question

public class Buzzers
{
private int num;
private int total;

public Buzzers()
{

}
public Buzzers(int num)
{
this.num = num;
}
public void setNum(int num)
{
this.num = num;
}
public int getNum()
{
return this.num;
}
//Method
public int Behavior(){
while(num != 0)
{
int remainder = num % 10;
if(remainder == 0 || remainder == 5 || remainder == 6 || remainder == 7)
remainder = 1;
else
remainder = 2;
total += remainder;
num = num/10;

}
return total;
}
}

Answer 1

You should not read the input as INT, if you want to process a leading "0".
I would prefer a String for that.

Answer 2

Coding Cat [sleeps on Java] okey i will try it tnx , nothing's wrong with my Behavior? Hmm

Answer 3

Redo you're welcome

Answer 4

Redo here a first version with input as String for leading zeros. Next I will do this with a more simple comparisation.

Answer 5

I have checked by not setting num value using constructor, by default num value is 0. Check the snippet

Parith (Faree) import java.util.Scanner;
public class Main{
public static void main(String[] args){
int num;
char choice;
Scanner in = new Scanner(System.in);
do {

System.out.println("Enter a number:");
num = in.nextInt();
while(num <=0){
System.out.println("--Invalid number--");
System.exit(0);

}
Buzzers b = new Buzzers(num);
System.out.println("Output is : "+b.Behavior());
System.out.println("Do you want to continue?(Yes/No)");
choice = in.next().charAt(0);
}
while(choice =='y'||choice == 'Y');
in.close();

}
}

Parith (Faree) If i try to run it and inputs 012 expected output is 5 but mine is 4 hmm 🤔 can you help me

public class Buzzers
{
private int num;
private int total;

public Buzzers()
{

}
public Buzzers(int num)
{
this.num = num;
}
public void setNum(int num)
{
this.num = num;
}
public int getNum()
{
return this.num;
}
//Method
public int Behavior(){
while(num != 0)
{
int remainder = num % 10;
if(remainder == 0 || remainder == 5 || remainder == 6 || remainder == 7)
remainder = 1;
else
remainder = 2;
total += remainder;
num = num/10;

}
return total;
}
}

Redo maybe you want to have a look at this one. It looks better:
