Bug in Multiple Format Strings challenge

This issue has been raised earlier here: https://teamtreehouse.com/community/level-bug-on-java-basics

When I use console.readLine() it doesn't work, but when I pass in a string console.readLine("Enter your name: "), it does.

readLine() method should work with or without an argument. Even if it is expected with an argument, it shouldn't throw an error.

JavaTester.java:116: error: method readLine in class MockConsole cannot be applied to given types;
String name = console.readLine();
                     ^
  required: String,Object[]
  found: no arguments
  reason: actual and formal argument lists differ in length
1 error

Mods, please look into this.

Multiple.java 
// I've imported java.io.Console for you.  It is stored in a variable called console for you.
String name = console.readLine();

Have you tried putting some text inside of your parenthesis. It kind of seems like that is what it is expecting. Just throw a set of quotation marks in there and see if that fixes it.

Thx Jeremy, but I already mentioned in my post above that it works fine with the argument. The issue is (at least I think it is) parameters in readLine() method are optional so it shouldn't throw syntax error when we don't pass the String argument.
