Thread: My code runs forever without output

There is probably a real easy solution for this but I am just missing it. The program is supposed to take an input file and then compare it to another file with a list of keywords and output the list of keywords with the number of times they occur in the test file (along with other tasks already achieved). The test file would have punctuation as well and I haven't quiet figured out how to omit those characters yet either. Any advise would be appreciated, assuming I am not completely off and need to rewrite the whole thing


import java.util.*;
import java.io.*;
import java.lang.*;

public class Project4 {



public static void main(String[] args) throws Exception
{


java.io.File file = new java.io.File("keywords.txt");
java.io.File testFile = new java.io.File("TestFile.txt");

Set<String> set = new HashSet<String>();

List<String> testList = new ArrayList<String>();




Scanner input = new Scanner(file);
Scanner testInput = new Scanner(testFile);

while (input.hasNext())
{
set.add(input.next());
// System.out.println(set);
}

TreeSet<String> treeSet = new TreeSet<String>(set);


//System.out.println(treeSet);

while (testInput.hasNext())
{
testList.add(testInput.next());

}

input.close();

TreeMap<String, Integer> map = new TreeMap<String, Integer>();

System.out.println(testList);


Iterator<String> iteratorSet = set.iterator();
Iterator<String> iteratorTest = testList.iterator();


while (iteratorSet.hasNext())
{
String key = iteratorSet.next();


while (iteratorTest.hasNext())
{
if (map.get(key) == null)
{
map.put(key, 0);
}
else
{

int value = map.get(key).intValue();
value++;
map.put(key,value);
}
}
}

Set<Map.Entry<String, Integer>> entrySet = map.entrySet();

for (Map.Entry<String, Integer> entry: entrySet)
System.out.println(entry.getValue() + "\t" + entry.getKey());
}


}

The code compiles and runs but the output should list the keywords and the number of occurances they appear in the test file.

The program sits running without ever producing an output.

i tried your code with empty keywords and TestFile, guess what programs doesn't run forever. i got an out put like

C:\Users\Arvind\java>java Project4
[]

C:\Users\Arvind\java>

Thank you, I found that earlier today. I was trying to figure out how to delete the post so not to embarrass myself online. I revised my code and thought I was making progress until this error showed up and can't find any reference to help understand it:

Ljava.lang.String;@13d4c61c

just click at thread tools at the start of your thread and mark it as solved!!
