String,format is something you might be familiar with if you've programmed in C/C++, Python or Java. The static format method takes a format string which contains special tokens that can be translated and replaced with an appropriate text.

Example:

<!-- language: lang-java -->

String.format("I am %d years old", 24); // I am 24 years old
String.format("Favorite sports team is %s and I like number %d", "foobar", 9); //Favorite sports team is foobar and I like number 9

String.format("Favorite sports team is %2$s and I like number %1$d", 9, "foobar");  //Favorite sports team is foobar and I like number 9

Hi Rex, To get a dynamic value we have to use this string format right?? , so is this the same format in all programming languages or it differs??

Thank you ..

I haven't seen a language that doesn't have this idea, but the syntax is a little different for each language. C, C++, and Java have a similar basic syntax in a lot of ways so this looks similar, but on the inside they're all very different languages in the way they handle communicating with the computer. For the most part, a lot of things, once you know one programming language, look similar across them all. They're made that way so that someone learning a new language can pick it up quickly if they've ever used any other language.
