解决方案（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）全部使用jarEntry列出jar文件中的类，但只能使用jarEntry作为水平遍历。当我想使用depth-first-traverse遍历jar文件中的类和文件夹时，我该怎么办？谢谢你的考虑。

添加到树
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 ();
}
}
}
显示树
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);
}
}

预期输入
如果输入jar文件的路径（例如org.objectweb.asm_3.3.1.v201105211655.jar）
预期输出
输出应该是文件结构（最好只包括包含类文件的类文件和文件夹。）。

修改
我使用的结构，我想存储结果：
class {
String data;
TJtree parent; //treenode
LinkedList<TJtree> childlist;
}
答案 0 :(得分：1)
按照出现的顺序阅读条目。使用完整路径名将它们添加到TreeMap。这将对它们进行排序并按照您想要的方式排列它们。要显示为树，请遍历完整路径名，以查看目录何时更改并正确显示。
e.g。
final NavigableMap<String, MyData> entryMap = new TreeMap<>();
// add each entry by full path to the entryMap
entryMap.put(fullpath, new MyData(... ... ...));
// later process the entries in the order required
File lastDirectory = new File("/");
for(Map.Enrty<String, MyData> entry : entryMap.entrySet()) {
File file = new File(entry.getKey());
MyData myData = entry.getValue();
if (!file.getParent().equals(lastDirectory.getParent()) {
// different directory
}
