Why do I get a compilation warning here (var args method call in Java)

Question

Source:

public class TestVarArgs {
  public void varArgsMethod(Object ... arr) {
     System.out.println(arr.getClass().getName());
     for(Object o : arr)          


        

Answer 1

One of the elegant ways to get rid off this warning: instead of tva.varArgsMethod(args) call tva.varArgsMethod(Arrays.stream(args).toArray()) explicitly showing that you pass multiple arguments. Another way to get rid off the warning is to use following call:

tva.varArgsMethod(Arrays.asList(args).toArray())

Anyway we have to convert the args to Array.
