Hi dkim18,

To change the text you can use setText:

    TextArea ta=new TextArea("first text");
    Button b=new Button("OK");

    ...
    b.addActionListener(
        new ActionListener(){
            public void actionPerformed(ActionEvent ev)
            {
                 // ta.getText();
                 ta.setText("second text");
            }
        }
    }

What do you mean by "to switch text" ? Can you give some examples ?

You can keep your sentences in arrays:

final String[] SENTENCES = { "xxx", "yyy", "zzz" };
int sentenceIndex = 0;


public void actionPerformed(ActionEvent ev)
{
    ta.setText(SENTENCES[sentenceIndex++ % SENTENCES.length]);
}
