Java optional parameters

Question

How do I use optional parameters in Java? What specification supports optional parameters?

Answer 1

You can do thing using method overloading like this.

 public void load(String name){ }

 public void load(String name,int age){}

Also you can use @Nullable annotation

public void load(@Nullable String name,int age){}

simply pass null as first parameter.

If you are passing same type variable you can use this

public void load(String name...){}
