Solutions(Get list of classes in package , How do I list the files inside a JAR file? , Listing the files in a directory of the current JAR file) are all used jarEntry to list classes in a jar file, however, jarEntry only can be used as level traverse. What should I do when I want to traverse classes and folders in a jar file using depth-first-traverse? Thank you for your consideration.

Add into the tree
static void getClasses(File pareFile, TJtree root){
TJtree parent, temp;
parent = root;
ArrayList<String> asArrayList = new ArrayList<String>();
File f = pareFile;
if(f.exists()){
try{
JarInputStream jarFile = new JarInputStream(new FileInputStream(f));
JarEntry jarEntry;
String [] jarEntryString;
String jarNodeNameString;
while(true) {
jarEntry=jarFile.getNextJarEntry();
if(jarEntry == null){
break;
}
asArrayList.add(jarEntry.getName());
Collections.sort(asArrayList);
jarEntryString = jarEntry.getName().split("/");
jarNodeNameString = jarEntryString[jarEntryString.length-1];
if(jarEntry.isDirectory()) {
temp = new TJtree();
temp.data = jarNodeNameString;
parent.childlist.add(temp);
parent = temp;
} else {
if(jarEntry.getName().endsWith (".class")) {
temp = new TJtree();
temp.data = jarNodeNameString;
parent.childlist.add(temp);
}
}
}
for (String tmpString : asArrayList) {
System.out.println("++"+tmpString);
}
} catch( Exception e){
e.printStackTrace ();
}
}
}
Display the tree
static void displaytree2(TJtree f , int level) {
String preStr = "";
for(int i=0; i<level; i++) {
preStr += " ";
}
for(int i=0; i<f.childlist.size(); i++) {
TJtree t = f.childlist.get(i);
System.out.println(preStr + "-"+t.data);
if(! t.childlist.isEmpty()) {
displaytree2(t, level + 1);
}
}
}

EXPECTED INPUT
If input a path of a jar file(e.g. org.objectweb.asm_3.3.1.v201105211655.jar)
EXPECTED OUTPUT
The output should be the files structure(It will be better to just include class files and folders containing class files.) in it.

EDIT
structure I used which I want to store the result:
class {
String data;
TJtree parent; //treenode
LinkedList<TJtree> childlist;
}
