Folder Explorer in Java with Source Code: We can develop Folder Explorer in java with the help of IO Stream, AWT/Swing with event handling. Let’s see the code of creating Folder Explorer in java.

 import java.io.*; import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.tree.*; /***********************************/ class Explorer extends JPanel implements ActionListener { JTextField jtf; JTextArea jta; JTree tree; JButton refresh; JTable jtb; JScrollPane jsp; JScrollPane jspTable;  String currDirectory=null;  final String[] colHeads={“File Name”,”SIZE(in Bytes)”,”Read Only”,”Hidden”}; String[][]data={{“”,””,””,””,””}};  ///////////////////////////////// Explorer(String path) {  jtf=new JTextField(); jta=new JTextArea(5,30); refresh=new JButton(“Refresh”);  File temp=new File(path); DefaultMutableTreeNode top=createTree(temp);  //if(top!=null)  tree=new JTree(top);  jsp=new JScrollPane(tree);  final String[] colHeads={“File Name”,”SIZE(in Bytes)”,”Read Only”,”Hidden”}; String[][]data={{“”,””,””,””,””}}; jtb=new JTable(data, colHeads); jspTable=new JScrollPane(jtb);  setLayout(new BorderLayout()); add(jtf,BorderLayout.NORTH); add(jsp,BorderLayout.WEST); add(jspTable,BorderLayout.CENTER); add(refresh,BorderLayout.SOUTH);  tree.addMouseListener( new MouseAdapter() { public void mouseClicked(MouseEvent me) { doMouseClicked(me); } }); jtf.addActionListener(this); refresh.addActionListener(this); } /////////////////////////////// public void actionPerformed(ActionEvent ev) { File temp=new File(jtf.getText()); DefaultMutableTreeNode newtop=createTree(temp); if(newtop!=null) tree=new JTree(newtop); remove(jsp); jsp=new JScrollPane(tree); setVisible(false); add(jsp,BorderLayout.WEST); tree.addMouseListener( new MouseAdapter() { public void mouseClicked(MouseEvent me) { doMouseClicked(me); } });  setVisible(true); } //////////////////////////////  DefaultMutableTreeNode createTree(File temp) { DefaultMutableTreeNode top=new DefaultMutableTreeNode(temp.getPath()); if(!(temp.exists() && temp.isDirectory())) return top;  fillTree(top,temp.getPath());  return top; } ////////////////////////////// void fillTree(DefaultMutableTreeNode root, String filename) { File temp=new File(filename);  if(!(temp.exists() && temp.isDirectory())) return; //System.out.println(filename); File[] filelist=temp.listFiles();  for(int i=0; i;>
