How does this program actually work...?
import java.util.Scanner;
class string
{
public static void main(String a[]){
int a;
String s;
Scanner scan = new Scanner(System.in);
System.out.println("enter a no");
a = scan.nextInt();
System.out.println("no is ="+a);
System.out.println("enter a string");
s = scan.nextLine();
System.out.println("string is="+s);
}
}
The output is:
enter the no
1234
no is 1234
enter a string
string is= //why is it not allowing me to enter a string here?
