Can we have parameterized constructor in java ?

absolutely
read up on sun's java tutorial
you could start on this page and follow the "trail" to learn more about constructors with different parameter lists

If you mean parameters to the constructor, then as Eric pointed out, the answer is obviously yes.

However, when you say "parameterized", do you mean parameterized types? Like so...

public class Tester<E> {
  private String tester;
 
  public <T extends Number> Tester (E core, T num) {
    tester = core.toString() + num.doubleValue();
  }
}

The answer is yes. Java supports generics with constructors -- just like the support for generic methods.
