A function in Java like string.Format("He is {0}","John") in .NET

[Nguyen Minh Duc]

I want a function in Java like
string.Format("He is {0}",John) in .NET
And the output is "He is John".

Please help me.
Thanks.

In Java 1.5 has a Formatter class. PrintStream also has a printf method.
And the String class also has format method, which would do the same.

The format is a bit different though. Not {0}, but C-like stuff. %s, %d, etc...

See java.text.MessageFormat. In Java 5 (JDK 1.5), your example would be

MessageFormat.format("He is {0}", "John");
