Java AVL bug

Hi i'm writing this code for an AVL tree. The program is working fine but it is not displaying the left and right child. Can you help me in fixing the problem. Here is my code:
package testavltree;

import java.io.*;
import java.util.ArrayList;
import java.util.ListIterator;

public class AVLProcess {

Search sr = new Search();
AVLTree ar = new AVLTree();

public AVLProcess() {
}

public AVLTree ReadInputFile(String input_file, String output_file) throws Exception {
String[] piece;

ArrayList<String> pos = new ArrayList<String>();
File file = new File(output_file);
FileWriter writer;

int currentCounter = 0;

try {
writer = new FileWriter(file);

FileReader reader;
try {
reader = new FileReader(input_file);
BufferedReader buff = new BufferedReader(reader);
String line = buff.readLine();


Node cleft;
Node cRight;


Node firstValue = null;
Node secondValue = null;


while (line != null) {



//If the line starts “insert”, get the value of node and insert to tree.
if (line.contains("insert")) {
piece = line.split(" ");
pos.add(piece[1]);

if (currentCounter == 0) {
firstValue = new Node(0);
secondValue = new Node(Integer.parseInt(piece[1]));
} else {
firstValue = secondValue;
secondValue = new Node(Integer.parseInt(piece[1]));
}

ar.AvlInsert(firstValue, secondValue);

} else if (line.contains("show inorder")) {
inOrder(ar.getRoot(), writer);

}


line = buff.readLine();
currentCounter++;

}

ar.AvlBalanceTree(ar.getRoot());

ListIterator iter = pos.listIterator();

while (iter.hasNext()) {
Node f = null;
String s = "";
int index = 0;
int key = Integer.parseInt(iter.next().toString());

f = new Node(key, null, null);
Node newNode = sr.search(ar.getRoot(), key);



cleft = newNode.getLeftNode();
cRight = newNode.getRightNode();

if (cleft != null) {
if (pos.contains(Integer.toString(cleft.getValue()))) {
index = pos.indexOf(Integer.toString(cleft.getValue()));
s += Integer.toString(index) + "," + Integer.toString(newNode.getValue());
}
} else {
s = "-," + Integer.toString(newNode.getValue());
}

if (cRight != null) {
if (pos.contains(Integer.toString(cRight.getValue()))) {
index = pos.indexOf(Integer.toString(cRight.getValue()));
s += "," + Integer.toString(index);
}
} else {
s += ",- ";
}

System.out.println(s);

}


ListIterator iters = pos.listIterator();

while (iters.hasNext()) {

System.out.println(Integer.toString(iters.nextIndex()) + iters.next());
}

reader.close();

} catch (FileNotFoundException e) {

writer.write("Input file Not Found..");
}
catch (IOException e) {
e.printStackTrace();
}
writer.close();

} catch (IOException e) {
e.printStackTrace();
}

return ar;
}
Insert method:
public void AvlInsert(Node nd, Node newNode) {
if (newNode.value < nd.value) {
if (nd.leftNode == null) {
nd.leftNode = newNode;
} else {
AvlInsert(nd.leftNode, newNode);
}
} else {
if (nd.rightNode == null) {
nd.rightNode = newNode;
} else {
AvlInsert(nd.rightNode, newNode);
}
}

AvlBalanceTree(nd);
}

Please edit your post and wrap your code in code tags for better displaying.

Solved it thanks anyways
