打印目录树

Question

我必须打印一个目录树(如树命令),例如:

 .
 +---A
 |   +---IMAGES
 |       +---BACKUP
 +---ADOKS
 |   +---ROZDZIAL_2
 |   +---ROZDZIAL_3
 |   +---ROZDZIAL_4
 +---AMSC2005
 |   +---AMSC2004
 +---FCCS2005
 |   +---source
 |   +---TMP
 +---LODZ2004
 +---ZAKOPANE2004
 +---DYDAKTYKA
 |   +---DYDAKTYKA_ISI
 |   |   +---COLLS
 |   |   |   +---Q1
 |   |   |   +---Q2
 |   |   |   +---RAZEM
 |   |   |       +---RYSUNKI_COLL1
 |   |   |       +---RYSUNKI_COLL2
 |   |   +---IMAGES
 |   |   +---src
 |   |   +---WYKLAD5
 |   +---DYDAKTYKA_PRG
 |       +---images
 |       +---POMOC
 +---DYDAKTYKA_KST
 |   +---images
 |   +---src
 +---DYDAKTYKA_WPR
     +---images
     +---src

我尝试使用以下代码:

private static void getInto(String p, int n) {
    File path = new File(p);
    File[] list = path.listFiles();

    for (int i = 0; i < list.length; i++) {
        if (list[i].isDirectorhowny()) {
            for (int j = 0; j < n; j++)
                if (WHAT HERE?)
                    System.out.print("|  ");
                else
                    System.out.print("   ");

            System.out.println("+--" + list[i].getName().toString());

            getInto(list[i].getPath(), n + 1);
        }
    }
}

我尝试了几个版本,但它仍然不起作用.这该怎么做？如果有什么条件？我知道很简单,但我不能这样做.

Answer 1

这就是我做到的.

代码

import java.io.File;
public class FileAssert {

/**
 * Pretty print the directory tree and its file names.
 * 
 * @param folder
 *            must be a folder.
 * @return
 */
public static String printDirectoryTree(File folder) {
    if (!folder.isDirectory()) {
        throw new IllegalArgumentException("folder is not a Directory");
    }
    int indent = 0;
    StringBuilder sb = new StringBuilder();
    printDirectoryTree(folder, indent, sb);
    return sb.toString();
}

private static void printDirectoryTree(File folder, int indent,
        StringBuilder sb) {
    if (!folder.isDirectory()) {
        throw new IllegalArgumentException("folder is not a Directory");
    }
    sb.append(getIndentString(indent));
    sb.append("+--");
    sb.append(folder.getName());
    sb.append("/");
    sb.append("\n");
    for (File file : folder.listFiles()) {
        if (file.isDirectory()) {
            printDirectoryTree(file, indent + 1, sb);
        } else {
            printFile(file, indent + 1, sb);
        }
    }

}

private static void printFile(File file, int indent, StringBuilder sb) {
    sb.append(getIndentString(indent));
    sb.append("+--");
    sb.append(file.getName());
    sb.append("\n");
}

private static String getIndentString(int indent) {
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < indent; i++) {
        sb.append("|  ");
    }
    return sb.toString();
}
}

结果

+--folder1/
|  +--a.txt
|  +--folder2/
|  |  +--b1.txt
|  |  +--b2.txt
|  |  +--b3.txt
|  |  +--folder3/
|  +--folder4/

}

        + "|  +--a.txt\n" + "|  +--folder2/\n" + "|  |  +--b1.txt\n"
        + "|  |  +--b2.txt\n" + "|  |  +--b3.txt\n" + "|  |  +--folder3/\n"
        + "|  +--folder4/\n";

@Test
public void testPrintDirectoryTreeComplex() throws Exception {
    // Setup
    File aFile = new File(folder1, "a.txt");
    assertTrue(aFile.createNewFile());
    File folder2 = new File(folder1, "folder2");
    assertTrue(folder2.mkdir());
    File b1File = new File(folder2, "b1.txt");
    assertTrue(b1File.createNewFile());
    File b2File = new File(folder2, "b2.txt");
    assertTrue(b2File.createNewFile());
    File folder3 = new File(folder2, "folder3");
    assertTrue(folder3.mkdir());
    File b3File = new File(folder2, "b3.txt");
    assertTrue(b3File.createNewFile());
    File folder4 = new File(folder1, "folder4");
    assertTrue(folder4.mkdir());

    // Invoke
    String actual = FileAssert.printDirectoryTree(folder1);
    // Verify
    assertEquals(EXPECTED_COMPLEX, actual);
}

}

文件 目录 打印 漂亮打印

Answer 2

这是我的解决方案:

(TreeNode该类是从那里复制的.)

public static String renderDirectoryTree(TreeNode<FileInformation> tree) {
    List<StringBuilder> lines = renderDirectoryTreeLines(tree);
    String newline = System.getProperty("line.separator");
    StringBuilder sb = new StringBuilder(lines.size() * 20);
    for (StringBuilder line : lines) {
        sb.append(line);
        sb.append(newline);
    }
    return sb.toString();
}

public static List<StringBuilder> renderDirectoryTreeLines(TreeNode<FileInformation> tree) {
    List<StringBuilder> result = new LinkedList<>();
    result.add(new StringBuilder().append(tree.getData().getPath().getFileName()));
    Iterator<TreeNode<FileInformation>> iterator = tree.getChildren().iterator();
    while (iterator.hasNext()) {
        List<StringBuilder> subtree = renderDirectoryTreeLines(iterator.next());
        if (iterator.hasNext()) {
            addSubtree(result, subtree);
        } else {
            addLastSubtree(result, subtree);
        }
    }
    return result;
}

private static void addSubtree(List<StringBuilder> result, List<StringBuilder> subtree) {
    Iterator<StringBuilder> iterator = subtree.iterator();
    //subtree generated by renderDirectoryTreeLines has at least one line which is tree.getData()
    result.add(iterator.next().insert(0, "??? "));
    while (iterator.hasNext()) {
        result.add(iterator.next().insert(0, "?   "));
    }
}

private static void addLastSubtree(List<StringBuilder> result, List<StringBuilder> subtree) {
    Iterator<StringBuilder> iterator = subtree.iterator();
    //subtree generated by renderDirectoryTreeLines has at least one line which is tree.getData()
    result.add(iterator.next().insert(0, "??? "));
    while (iterator.hasNext()) {
        result.add(iterator.next().insert(0, "    "));
    }
}

使用此输出:
