Variable Parameter list

Question

I would like to know if Java supports vairable number of parameter for a method, which is supported by C++.

Answer 1

It does not.
You can archive the same goal by means of an individual method per parameter like this:
public class VariableParameter {
    private String parA, parB, parC;
    public VariableParameter setParamA(String parA) { this.parA = parA; return this; }
    public VariableParameter setParamB(String parB) { this.parB = parB; return this; }
    public VariableParameter setParamC(String parC) { this.parC = parC; return this; }
    public String toString() {
     return "parA==" + parA + "   parB==" + parB + "   parC==" + parC;
    public static void main(String[] args) {
     VariableParameter mc = new VariableParameter();
     mc.setParamA("first").setParamC("third");
     System.out.println(mc);
}THis way one codeline is enough to call as many or as few of the set methods as you want to call.
Beware that these set methods are not set methods in the java beans sense, ebcause they return this instead of void.
