i was going through a blog on
I got the guy using String.format().
I could not get why he was using this.
if i write this
Let private int constant = 1; 1. System.out.println(String.format("%d", constant)); 2. System.out.println(constant));
Both will give same result i.e. 1.
Is java people included this because of giving feel of c/c++?
Is there any important role of this method?

Check out the API docs for the Formatter class to get a better understanding of the method.

Also, it produces Strings similar in format to what is described
in the Java™ Tutorials

In the example you gave, yes it is pointless. However String.format(...) is capable of much more complicated and useful stuff.
I agree. Here's the link:
