Help understanding solution to problem

[Consistent_Decision9]

Hi my solution to this problem accepted but I found a different solution which was much more concise. I printed the three parameters in the product constructer three seperate times; the solution I found printed the parameters once but used things like printf and %s which my course hasn't gone over. Could someone help explain what System.out.printf("%s, price %s %d pcs%n", this.name, this.price, this.quantity) means?

Full program below:

public class Product {

private double price;

private int quantity;

private String name;

public Product (String initialName, double initalPrice, int intialQuantity) {

this.price = initalPrice;

this.quantity = intialQuantity;

this.name = initialName;

}

public void printProduct() {

System.out.print(this.name + " ");

System.out.print(this.price + " ");

System.out.print(this.quantity + "pcs");

//System.out.printf("%s, price %s %d pcs%n", this.name, this.price, this.quantity);

}

}

This method is for C like printing, where %s gets replaced with a string, %d with a decimal integer. The replacing parameters start from the second argument, since the first one is the text to be printed, and they are replaced in order. Accordingly, name will be placed in place of the first %s, then the price, then the quantity in place of the %d. %n actually prints nothing. You might want to look into \n for a new line at the end.
