How do I copy to the system clipboard in/using Java on Windows 10? [duplicate]

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).

For more information see official documentation

For reference:

static void copyToClipboard(String text) { java.awt.Toolkit.getDefaultToolkit().getSystemClipboard() .setContents(new java.awt.datatransfer.StringSelection(text), null); }

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

For reference here are the copy and paste functions from/to the system clipboard written in Clojure (so related to Java):

(defn copy [s] (-> (java.awt.Toolkit/getDefaultToolkit) .getSystemClipboard (.setContents (java.awt.datatransfer.StringSelection. s) nil))) (defn paste [] (-> (java.awt.Toolkit/getDefaultToolkit) .getSystemClipboard (.getContents nil) (.getTransferData java.awt.datatransfer.DataFlavor/stringFlavor))) (copy "Hello!") (paste) ;=> "Hello!"
