Is there a general string substitution function similar to sl4fj?

String.format

[java]String str = String.format("Action %s occured on object %s.",
objectA.getAction(), objectB);

[/java]

Or

[java]String str = String.format("Action %s occured on object %s with outcome %s.",
new Object[]{objectA.getAction(), objectB, outcome});

[/java]

You can also use numeric positions, for example to switch the parameters around:

[java]String str = String.format("Action %2$s occured on object %1$s.",
objectA.getAction(), objectB);
[/java]
