Yes, varargs were introduced in version 1.5. See Varargs.

[Ireneusz Kordal]

var-args = variable number of arguments.

Example:

 
public class Main{
    static void m(String ... s){
        System.out.println("Number of args = " + s.length);
        for( String x : s )
              System.out.print(x + " ");
        System.out.println();
    }
    public static void main(String ... arg){
        m();
        m("a");
        m("a","b");
        m("x","y","z","a","b","c");
    }
}

varargs indicate that you can pass a variable number of arguments or an array in a method or constructor.
