To add this library to your project, click on JitPack badge. You can also manually add Jar file, you can find jar file in release section.
Demo: I have created two classes for printing FilesStructure.
public class Main {
public static void main(String[] args) {
File file=new File("./src");
FileTreePrinter treePrinter=new FileTreePrinter(file);
treePrinter.visitAndPrint();
// or
// StringBuilder sb=treePrinter.visitAndReturn();
// sout(sb);
}
}This code will produce below output.

public class Main {
public static void main(String[] args) {
File file=new File("./src");
FileTreePrinterColored treePrinter=new FileTreePrinterColored(file);
treePrinter.visitAndPrint();
// or
// StringBuilder sb=treePrinter.visitAndReturn();
// System.out.println(sb);
}
}This code will produce below output.
Also in case of FileTreePrinterColored you can set custom colors.
public class Main {
public static void main(String[] args) {
File file=new File("./src");
FileTreePrinterColored treePrinter=new FileTreePrinterColored(file);
treePrinter.setFolderColor(Color.RED);
treePrinter.setHiddenFolderColor(Color);
treePrinter.setExecutableFileColor(Color);
treePrinter.setNonExecutableFileColor(Color);
//or
treePrinter.setNonExecutableFileColor(Color.valueOf("color asci"));
treePrinter.visitAndPrint();
// or
// StringBuilder sb=treePrinter.visitAndReturn();
// System.out.println(sb);
}
}If you want to print other than file tree than you can use TreePrinter abstract class. In that case you need to implement three methods.
Object obj;
TreePrinter treePrinter=new TreePrinter(obj) {
@Override
public Object[] getChild(Object obj) {
return new Object[0];
}
@Override
public String getValue(Object obj) {
return null;
}
@Override
public boolean isLeaf(Object obj) {
return false;
}
};
// Here obj is the root of TreeStructure.for ie. if you want to print BinaryTree than you can do something like below...
Object obj; //here obj is root of Binary tree
TreePrinter treePrinter=new TreePrinter(obj) {
@Override
public Object[] getChild(Object obj) {
Node node=(Node)obj;
return new Object[]{node.left,node.right};
}
@Override
public String getValue(Object obj) {
return ((Node)obj).getValue();
}
@Override
public boolean isLeaf(Object obj) {
Node node=(Node)obj;
return node.left==null && node.right==null;
}
};
// Here obj is the root of TreeStructure.
