如何在JTextField中对齐文本？

Question

Here is my code:

try{
    Font font1=new Font("SansSerif",Font.ITALIC,20);
    JTextField levi=new JTextField(20);
    levi.setBounds(107,10,246,100);
    levi.setForeground(Color.black);
    levi.setHorizontalAlignment(SwingConstants.BOTTOM);
    levi.setFont(font1);
    levi.setBorder(nue);
    lin.add(levi);
} catch(Exception ex) {
    JOptionPane.showMessageDialog(null, ex);
}

When I run the program i got this exception

Answer 1

If you check the javadocs for JTextField , the only valid keys for the setHorizontalAlignment() method are:

 JTextField.LEFT JTextField.CENTER JTextField.RIGHT JTextField.LEADING JTextField.TRAILING 

Passing in SwingConstants.BOTTOM will throw an exception.
