How would I overload method in an interface?

Question

if I have this interface

public interface someInterface {
  // method 1
  public String getValue(String arg1);
  // method 2
  public String getValue(String arg1         


        

Answer 1

If the second value can be considered optional in a sense and you always have the 2 arguments when calling you could create a wrapper class which implements the 2 parameter interface passing the 1 parameter implementation as a constructor parameter and calling that in the method, e.g. something like this:

interface A{
  method1(P1)
}

interface B{
  method2(P1, P2)
}

class Wrap implements B{
  Wrap(A impl)

  override method2(P1, P2){
    call impl.method1(P1)
  }

}
