获取错误-线程“ AWT-EventQueue-0”中的异常java.lang.IllegalArgumentException：文本不能为null或为空

Question

Trying to use Text Area to send String to IBM Watson.

Could do this by hard coding String. I want to be able to input my own text in JTextArea.

Answer 1

Move String text = textArea.getText(); inside the actionPerformed method like this:

public void actionPerformed(ActionEvent e) {
            String text = textArea.getText();
            Profile profile = service.getProfile(text).execute();  
            System.out.println(profile);


                }
