JTextField, removing end characters

Is there an inbuilt function that can remove the last character from a JTextField, or is the only way to set the string to a new string with the last character removed?

JTextField textfield = new JTextField(sometext);

// What I'm looking for
textfield.removeLastCharacter();

// What I'm using
char[] text = textfield.getText().toCharArray();
String string = "";
for (int i = 0; i < text.length - 1; i++) string += text[i];
textfield.setText(string);

Do this. it works for java programs. Use your Textfield's name for textField

textField.setText(textField.getText().substring(0, textField.getText ().length() - 1));

Document doc = textField.getDocument();
doc.remove(...);

You will also need to get the length of the Document so you know which character to remove. Check out the Document API for the appropriate method.
