The quickest way to get the reference of Clipboard is via Toolkit. JTextField textField=new JTextField(40); Toolkit toolkit=textField. getToolkit(); Or, by using the static function defined in the Toolkit class.
Select "File -> Exit" from the Policy Tool window to close the policy editor. Restart your browser. You should now be able to copy and paste between Java Swing applets and other computer applications such as Microsoft Excel. Please note to use Ctrl-C and Ctrl-V to copy and paste.
A class that implements a mechanism to transfer data using cut/copy/paste operations. FlavorListener s may be registered on an instance of the Clipboard class to be notified about changes to the set of DataFlavor s available on this clipboard (see addFlavorListener(java. awt.
datatransfer. StringSelection. Create a StringSelection with an empty String as selection to set as the clipboard contents to clear it.
This works for me and is quite simple:
Import these:
import java.awt.datatransfer.StringSelection;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
And then put this snippet of code wherever you'd like to alter the clipboard:
String myString = "This text will be copied into clipboard";
StringSelection stringSelection = new StringSelection(myString);
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(stringSelection, null);
This is the accepted answer written in a decorative way:
Toolkit.getDefaultToolkit()
.getSystemClipboard()
.setContents(
new StringSelection(txtMySQLScript.getText()),
null
);
The following class allows you to copy/paste a String to/from the clipboard.
import java.awt.*;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.StringSelection;
import static java.awt.event.KeyEvent.*;
import static org.apache.commons.lang3.SystemUtils.IS_OS_MAC;
public class SystemClipboard
{
public static void copy(String text)
{
Clipboard clipboard = getSystemClipboard();
clipboard.setContents(new StringSelection(text), null);
}
public static void paste() throws AWTException
{
Robot robot = new Robot();
int controlKey = IS_OS_MAC ? VK_META : VK_CONTROL;
robot.keyPress(controlKey);
robot.keyPress(VK_V);
robot.keyRelease(controlKey);
robot.keyRelease(VK_V);
}
public static String get() throws Exception
{
Clipboard systemClipboard = getSystemClipboard();
DataFlavor dataFlavor = DataFlavor.stringFlavor;
if (systemClipboard.isDataFlavorAvailable(dataFlavor))
{
Object text = systemClipboard.getData(dataFlavor);
return (String) text;
}
return null;
}
private static Clipboard getSystemClipboard()
{
Toolkit defaultToolkit = Toolkit.getDefaultToolkit();
return defaultToolkit.getSystemClipboard();
}
}
For JavaFx based applications.
//returns System Clipboard
final Clipboard clipboard = Clipboard.getSystemClipboard();
// ClipboardContent provides flexibility to store data in different formats
final ClipboardContent content = new ClipboardContent();
content.putString("Some text");
content.putHtml("<b>Some</b> text");
//this will be replaced by previous putString
content.putString("Some different text");
//set the content to clipboard
clipboard.setContent(content);
// validate before retrieving it
if(clipboard.hasContent(DataFormat.HTML)){
System.out.println(clipboard.getHtml());
}
if(clipboard.hasString()){
System.out.println(clipboard.getString());
}
ClipboardContent can save multiple data in several data formats like(html,url,plain text,image).

I found a better way of doing it so you can get a input from a txtbox or have something be generated in that text box and be able to click a button to do it.!
import java.awt.datatransfer.*;
import java.awt.Toolkit;
private void /* Action performed when the copy to clipboard button is clicked */ {
String ctc = txtCommand.getText().toString();
StringSelection stringSelection = new StringSelection(ctc);
Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
clpbrd.setContents(stringSelection, null);
}
// txtCommand is the variable of a text box
