can someone explain it in simply so that my noob self can understand?

Answer 1

Are you familiar with printf() of C? Then it'll be easy for you to understand how the placeholders work.

int num = 4;
char letter = 'A';
double value = 5.8;

System.out.printf("%d %c %.2f", num, letter, value);

// output : 4 A 5.80

Answer 9

It's a regular print function you can use in order to print strings. Try to learn all of those functions because you are going to need them in order to code better. Otherwise it might affect you with errors which spend a lot of precious time. Of course you can always use an app to detect those errors for you. I have heard of one called checkmarx you can try.
Anyway, good luck!
