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.

Hello,

Thank you for reaching out. It seems like you are on the right track by following your teacher's instructions to put the StdIn.java file in the same folder as your source file. However, there may be some additional steps you need to take in order for the program to work properly.

First, make sure that you have properly imported the StdIn.java file into your program. This can be done by using the "import" statement at the beginning of your code, like this: "import StdIn;". This will allow your program to access the methods and commands from the StdIn.java file.

Next, check to make sure that you are using the correct syntax when using the StdIn and StdOut commands in your program. For example, when using StdIn.readIn(), make sure that you are passing in the appropriate parameters and using the correct data types.

If you are still experiencing errors, it may be helpful to review the documentation for the StdIn.java file or reach out to your teacher for additional support. Sometimes, there may be specific instructions or guidelines for using the StdIn and StdOut commands in your program.

I hope this helps and good luck with your program!
