difference between printf and println in java? [duplicate]

Question

Just came to know that java does has a method named printf, then what is the difference between printf & println?

Troika

printf is like the C printf function, "print format", the other is a more (or less) updated version, which doesn't require a format and value list...What does the JavaDoc's tell you? – Picrite

@Picrite than what is the use of it if we have format and printf the same ? – Troika

Because for many, printf is confusing and be difficult to use if you've not used it before. You can use println("Say " + word) or printf("Say %s%n", word), which one is generally more easier to read? C doesn't have a String in the sense that Java does, so allowing println simplifies the process – Picrite

@shikjohari kindly read the question properly as it's about difference and not about which one is better and I had gone through your mentioned before posting this question. – Troika

@BhargavModi Well if you go through the answer of that question, you ll understand why I said this as a dupclicate. Read the asnwers also properly :) – Sheronsherourd

The difference is not very important since both should be avoided. It's better to use a logger to output your text. And if you need your logged text to be formatted, use String.format. – Hiramhirasuna

Answer 1

System.out.println(); is efficient for simply printing a line of text. If the line of text needs to be formatted (ex: alignment (left-justified, etc.), etc.), then System.out.printf(); would be used.
