        public static void main(String[] args) {
                for(char c = 'A'; c < 'Z'; c++) {
                        for(int i = 0; i < 2; i++) {
                                System.out.println("seat "+c+i);
                        }
                }
        }
}

Answer 1

ANSWER: Explanation is given along with code as comment and output also given for this.

CODE:

public class LoopQ
{
   public static void main(String[] args) {
   for(char c = 'A'; c < 'Z'; c++) {// this loop will run from A to Z and for every iteration of this loop inner loop will run two times so when C=A then inner loop will run two times for i=0 to i=1 and print char A0 and A1 and after that B0 B1 and after that C0 C1 and so on...
for(int i = 0; i < 2; i++) {
System.out.println("seat "+c+i);
}
}
   }
}

OUTPUT:
