Why the first loop not working?

Question

public class Program
{
public static void main(String[] args) {

int a = 1;
int b= 1;

while (a <= 11){
while (b<= 10){
System.out.println(a + "x" + b + "=" + a*b);
b++;
}
a++;
}

}
}

Answer 1

public class Program
{
public static void main(String[] args) {

int a = 1;
int b;

while (a <= 11){
b= 1;
while (b<= 10){
System.out.println(a + "x" + b + "=" + a*b);
b++;
}
System.out.println();
a++;
}

}
}

It works fine .The second loop run only once..Now it is corrected
