Copy/paste this code into a file Minimum.java:

public class Minimum {

    public static void main (String [] args) throws IOException {
	// Create a buffered reader
	// need only one buffered reader for all your reading
	BufferedReader in = new BufferedReader(
			new InputStreamReader(System.in));
	// string for storing a line of input
	String line;

	// Read one integer
	// prompt the user:
        System.out.print("Please enter an integer: ");
	// read a line of input:
	line = in.readLine();
	// extract the integer from the entered data:
	int n = Integer.parseInt(line);

	// Read another integer
	// prompt the user:
        System.out.print("Please enter another integer: ");
	// read a line of input:
	line = in.readLine();
	// extract the integer from the entered data:
	int m = Integer.parseInt(line);

	// fill in your code here
	
	// write two versions: one when the smaller number is displayed,
	// the other when it's stored in a variable

    }
}

This is an example from CSci 1211 course.
