3,931 PointsI have a problem with the code challenge : Java basics - Multi format String
I don't quite understand why i won't pass ( i got stuck in the first step , where i need to create a variable called name and accept input using readLine() ) what i did is :
String name = console.readLine();
// I've imported java.io.Console for you. It is stored in a variable called console for you.
String name = console.readLine();

JavaTester.java:116: error: method readLine in class MockConsole(some class Treehouse made) 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
This means that they have a class called MockConsole that doesn't have the required arguments. The readLine method here is expecting an argument of String and an object array.
So in this case it doesn't look like they are using java.io.Console as stated, otherwise your code should have worked and would have complied on your system if you were working locally.
In this case it looks like they are expecting you to go off the example from the first video:
String name = console.readLine("Enter your name: ");
Hope this helps.

String name = console.readLine("What is your name?");
