Below program when run will lead to an error which tells us that control variable is not visible after loop

public class Main
{
   public static void main(String[] args) {
int ct=0;
while(ct<=10)
{
int j=1;
  
ct++;
}
try {
System.out.println(j);
System.out.println("It is visible outside loop");
} catch(Exception e) {
System.out.println("It is not visible outside loop");
}
  
  
   }
}

Kindly revert for any queries
