Java Why is StdIn.java Not Working in My Program?

[Hiche]

I want to use StdIn and StdOut in my program as instructed. Our teacher told us to put the StdIn.java file inside the same folder as the source file (the program I am writing). But that is not working. Always gives me an error when I use the commands.

Am I doing it wrong? Is there another way?

StdOut.print or StdIn.readIn()

(for example)

I think you might be missing an import statement at the top of your code. It would look like this:

import StdIn;
// any other imports
.
.
.
<your code>

I added the import statement but the error keeps appearing: "StdIn cannot be resolved". I'm positive that I placed the StdIn.java file in the same directory as my program. I am using Eclipse as an IDE so the .java files are usually in a folder called src, where I also put the StdIn.java.

Never mind. I just had to refresh my project. The import statement is not really needed when we place the .java files in the same directory.
