Java: Does String.Format exist in Java like in C#?

Question

Something I discovered I like about C# are properties & String.Format.

Does something like String.Format from C# exist in Java?

C# ex:

int myNum = 2; 
int myNumSq = myNum * myNum;
String MyString = String.Format("Your lucky numbers are: {0}, & {1}", myNum, myNumSq);

Yes, the class in question is "MessageFormat":

MessageFormat.Format("Your lucky numbers are: {0}, & {1}", myNum, myNumSq);

(Not sure if auto-boxing will work correctly in this case - you might need to convert the int to an Integer first)

Auto boxing works, its for precisely this use case it was introduced.

It' even called String.format():

String myString = String.format("Your lucky numbers are: %d, & %d", myNum, myNumSq);

This method is available since Java 1.5.
