This is to test a balanced tree. I need help testing an unbalanced tree the same way

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.*;
public class Test {
public static final String INPUT = System.getProperty("user.dir") + "/input/";
public static final String OUTPUT = System.getProperty("user.dir") + "/output/";
public static void main(String[] args) throws FileNotFoundException {
TreeMap map = new TreeMap();
long startTime;
long totalTime = 0;
for(int i = 1; i <= 77;i++) {
Scanner scnr = new Scanner(new File("c:/Users/tvazq/IdeaProjects/hw2/resources/" + i + ".okpuncs"));
while(scnr.hasNext()) {
String word = scnr.next();
startTime = System.nanoTime();
if(!map.containsKey(word))map.put(word, 0);
map.put(word, 1 + map.get(word));
totalTime += (System.nanoTime() - startTime);

}
}
PrintWriter out = new PrintWriter("c:/Users/tvazq/IdeaProjects/hw2/part2" + "frequencies.txt");

startTime = System.nanoTime();
Set allWords = map.keySet();
totalTime += (System.nanoTime() - startTime);
for(String word: allWords) {
startTime = System.nanoTime();
int frequency = map.get(word);
totalTime += (System.nanoTime() - startTime);
out.printf("%s\t%d\n", word, frequency);
out.flush();
}
out.close();
System.out.printf("%.3f ms", totalTime/1e6);
}
}
