Issue
I have developed a swing GUI in which I try to populate a text area with the text from another text area using button.
Code:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jTextArea2.setText(4.0+" "+jTextArea1.getText().trim());
jTextArea1.setText("")
}
It is working fine if I enter the text first time in TextArea1 and hit the button to populate the TextArea2. But if I enter a new text in TextArea1 and hit the button instead of appending it to the TextArea2 it replaces the text.
Please suggest me how to correct the same.
Solution
You should invoke append
no setText
jTextArea2.append(4.0+" "+jTextArea1.getText().trim());
