What does "%s" mean? what does it do?
I see it in the coding of the display message.

Hello

"%s" is a format specifier for the printf function in Java language. The printf function accepts a format string, which specifies a method for displaying a number of parameters into a string. Any character in this string is displayed literally, and the parameters are placed in this string in positions marked by format specifiers, usually introduced by a % character.
Examples of format specifiers are:
- %s = string parameter
- %d = integer parameter
- %f = float parameter
etc

So an example should look like this:

printf("The number you want to display is: %d",number);
printf("My name is %s and I'm %d years old.", name,age);

So if number=123 and name="George" and age=26, the output should be:

The number you want to display is: 123
My name is George and I am 26 years old.

I hope you understand something from this.
Have a nice day.
