Java has had varargs since Java 1.5 (released September 2004).

A simple example looks like this...

public void func(String ... strings) {     for (String s : strings)          System.out.println(s); } 

Note that if you wanted to require that some minimal number of arguments has to be passed to a function, while still allowing for variable arguments, you should do something like this. For example, if you had a function that needed at least one string, and then a variable length argument list:

public void func2(String s1, String ... strings) {  }
