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); 

Answer 1

Yes, the class in question is "MessageFormat":

http://download.oracle.com/javase/6/docs/api/java/text/MessageFormat.html

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)

Answer 2

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.

Answer 3

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