Java program doesn't print some code to console

Question

I'm trying to compare the execution times of brute force search vs binary search on a whitelist.

Problem

When I run java BinarySearch tinyW.txt < tinyT.txt , elapsedTime and the "test" string are not output to console but they are output to console for java BruteForceSearch tinyW.txt < tinyT.txt .

Note : I'm using external library from here to do the I/O operation.

Brute force

public class BruteForceSearch {

    public static int rank (int key, int[] a) {
        for(int i = 0; i < a.length; i++)
            if(a[i] == key)
                return i;

    return -1;
    }

    public static void main(String[] args) {
        long startTime = System.currentTimeMillis();
        System.out.println("test");

        // read the integers from a file
        In in = new In(args[0]);
        int[] whitelist = in.readAllInts();

        // sort the array
        Arrays.sort(whitelist);

        // read integer key from standard input; print if not in whitelist
        while (!StdIn.isEmpty()) {
            int key = StdIn.readInt();
            if (rank(key, whitelist) == -1)
                StdOut.println(key);
        }

        long stopTime = System.currentTimeMillis();
        long elapsedTime = stopTime - startTime;
        System.out.println("elapsed time: " + elapsedTime);
    }
}

Binary search

public class BinarySearch {

    public static int rank(int key, int[] a) {
        int lo = 0;
        int hi = a.length - 1;
        while (lo <= hi) {
            // Key is in a[lo..hi] or not present.
            int mid = lo + (hi - lo) / 2;

            if (key < a[mid]) hi = mid - 1;
            else if (key > a[mid]) lo = mid + 1;
            else return mid;
        }
        return -1;
    }

    public static void main(String[] args) {
        long startTime = System.currentTimeMillis();
        System.out.println("test");

        // read the integers from a file
        In in = new In(args[0]);
        int[] whitelist = in.readAllInts();

        // sort the array
        Arrays.sort(whitelist);

        // read integer key from standard input; print if not in whitelist
        while (!StdIn.isEmpty()) {
            int key = StdIn.readInt();
            if (rank(key, whitelist) == -1)
            StdOut.println(key);
        }

        long stopTime = System.currentTimeMillis();
        long elapsedTime = stopTime - startTime;
        System.out.println("elapsed time: " + elapsedTime);
    }
}

Answer 1

I copied all those files to a single directory, namely the files:
BinarySearch.java, In.java, StdIn.java, StdOut.java, tinyT.txt, tinyW.txt

Then ran the following:

javac BinarySearch.java

then:

D:\temp\BinarySearch>java BinarySearch tinyW.txt < tinyT.txt
test
50
99
13
elapsed time: 249

Notice it printed the output...

Can you try my same steps?
