General Java Help

[ST34LTH]

Hey Ive been learning to use Java through videos and thankfully its going pretty good, just some things I dont understand listed below:

	public String toString()
	{
		return String.format("%d:%02d:%02d %s", ((hour==0||hour==12)?12:hour%12), min, sec,(hour<12? "AM": "PM"));
		
	}

In the above statement can someone tel me what "%" and "%s" does,

	public void saying()
	{
		System.out.printf("Your first GF was %s\n", getName());
	}

and this one can someone tell me what "%s\n" does,

This has just been playing on my head abit, tried google but that didnt help.

Thanks very much for your time and support

Read the API documentation for the Formatter class; that class formats Strings according to those % format specifiers and its used by other classes.

kind regards,
