My assessment is making a tree from a text file as follows: -reading a file line by line
-making a binary tree from it
- traverse by level the binary tree
- posting the traversal result to the same file without overwriting the text file- it is required to be append to the bottom of the text file
(i have to do this in 4 languages: c#,PHP from Xampp,java, python)
-----------------------------
i read the file with this script in java:


public class FileToStringArray {

private String strLine;
private String[] stringArray;
private FileInputStream in;
private BufferedReader br;
private int sizeOfArray = 0;
private File file = null;
private FileReader fr = null;
private LineNumberReader lnr = null;
private String fileName;

public FileToStringArray(String fileName){
this.fileName = fileName;
countLines();

}

private void countLines(){ //cound the lines and puts the number into sizeOfArray
try{

file = new File(fileName);
fr = new FileReader(file);
lnr = new LineNumberReader(fr);
String line = "";
while ((line = lnr.readLine()) != null){
sizeOfArray++;
}
}catch(Exception e){
System.out.println("Bad File");
System.out.println(e);
}
sizeOfArray--;
}//end of countLines

public String[] getString(){ //makes and array of size sizeOfArray and fills it with text
try{

in = new FileInputStream(fileName);
br = new BufferedReader(new InputStreamReader(in));

stringArray = new String[sizeOfArray];

for (int j = 0; j < stringArray.length; j++){
stringArray[j] = br.readLine();


}in.close();
}
catch(Exception e){
System.out.println("Bad File");
System.out.println(e);
}

return stringArray;
}//end of get string
public static void main(String arg[]){

String x[] = new FileToStringArray("file.txt").getString();

for(int i = 1; i<x.length;i++){
System.out.println(x[i]);
}
}//end of main
}//end of class
---------------
but how i can make a binary tree from this point???

please help!!!!!!!!!

Are you sure you should be asking for help on an assessment?

that's your option! i don't condemn anyone who don't have any interest to help !!! i wish you all the best!
maybe i've made a mistake from my side!!! sorry......

If I were the organization conducting the assessment, I would search on the Internet for elements from each person's code (the code you've shown us, for example) to see whether anyone was getting outside help, which would imply cheating. For the sake of your own continuing moral maturation (a journey none of us ever finish), I hope they catch you.

I've quoted your code, so you can't edit it away. Your only guarantee against being caught is to completely rewrite your code.

Go and sin no more.

I don't know what are you talking about!!!! i am not a thiever and you are totally wrong from all points of view!!!!
maybe you have another problem which doesn't have any related link with my task!!! I haven't applied for any kind of job as you are sustaining!!! you are totally wrong !! nobody will asses my knowledge !!!!!i am not a developer and i am not gaining my life from that ...i have attended high level studies ... i am a wide minded person...
don't talk about what you really don,t know...you really overcome and overestimated you.

If that is really true, then you have nothing to fear.

Best wishes.

I can see that English is not your first language. Perhaps you chose the wrong word when you said "assessment." What did you actually mean?

Usually, a programming assessment is a test given by a potential employer to test the skill levels of candidates.

I thought that was what it was, too. Particulary because:

you really don't understand anything!! i had to asses my knowledge!!!! you are too narrow minded!!
i will not complicate anymore with this forum !!
also it demonstrated me that is very useless!!
this forum is totally useless!!!!!!!!!!!!!!!!!!!!!!!!!!!1

I will delete my account definitely......................
