Java function parameter Default Value

Java function parameter Default Value

Today, you need to set the default value of Java function parameters and find that the method in other languages does not work.

Java only seems to be implemented through function overloading.

 

Function parameter Default Code Java code

1. Public class parameterdefault {
3. /**
4. * @ Param ARGs
5. */
6. Public String getname (string givenname, string familyname ){
7. Return givenname + "." + familyname;
8. }
9. Public String getname (string givenname ){
10. Return getname (givenname, "xie ");
11. }
12. Public static void main (string [] ARGs ){
13. // Todo auto-generated method stub
14. Parameterdefault = new parameterdefault ();
15. System. Out. println (parameterdefault. getname ("AAA "));
16. System. Out. println (parameterdefault. getname ("AAA", "Liu "));
17. }
