Is there a general string substitution function similar to sl4fj?

String.format

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

Or

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

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

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