Question

I think allowing recursion can be very handy sometimes, not because I can code in “recursion” but rather because I can save some code space for some cases like below

public class SomeClass
{
   private int a;

   SomeClass(int a)
   {
      this.a = a;
   }

   SomeClass()
   {
      SomeClass(3);
   }
}

This is especially effective when one constructor tries to take advantage of another that contains big chunks of code.

However, Java clearly doesn’t support this feature, and I believe it doesn’t for a very good reason. Could anyone care to explain why though?

Answer 1

Java does support this, but you need to use different syntax:

this(3);
