They are format specifiers used in some methods like printf() to format the string.

  • The %s is replaced with the times value (below in the example).
  • The %n tells the console print it in a new line.

Example:

        Integer times = 3;
        System.out.printf("How many times you should try: %s%n", times);
        times = times + 1;
        System.out.printf("How many times he should try: %s%n", times);

output would be like:

How many times you should try: 3
How many times he should try: 4

Example without %n: if we delete the %n it will print the output in the same line:

        Integer times = 3;
        System.out.printf("How many times you should try: %s", times);
        times = times + 1;
        System.out.printf("How many times he should try: %s", times);

output would be like:

How many times you should try: 3How many times he should try: 4
