只需按一下按钮，即可从JTextfield将文本复制到剪贴板

Question

After working on a GUI that prints your Text backwards (Hello = olleH) , Now I want to create a little Button that lets you copy the Outcome in a way you can paste it anywhere else (example in any Editor). I am using a JTextfield called jtxtoutcome . I don't know what else I could say, I guess this is pretty accurate.

This is how I use to change the outcome Textfield.:

jtxtoutcome.setText(backwards);

Answer 1

You can copy the text with the following code

StringSelection stringSelection = new StringSelection (txtField.getText());
Clipboard clpbrd = Toolkit.getDefaultToolkit ().getSystemClipboard ();
clpbrd.setContents (stringSelection, null);

The text will be copied to your clip board and then it can be pasted anywhere. In any editor.
