Question

I realize that was not a very descriptive question, but I wasn’t sure how else to state it..

I wrote an interpreter, Tiny_Int.java, for a made up language called “tiny”. All I need to know is how to run the interpreter with a specified tiny file like so:

java Tiny_Int <Sample.tiny

It may be helpful to know I am using this to read the tiny file

FileReader fileReader = new FileReader(file); //file being the Sample.tiny
BufferedReader bufferedReader = new BufferedReader(fileReader);

Answer 1

You are redirecting the file to the Java command, therefore you should read the content from standard input stream (System.in) using,

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

Use br.readLine() to read each line until it returns null.
