The correct expression to read the contents of a text field holding an integer is Integer.parseInt(textField.getText()). This expression will convert the String returned by getText() into an integer value. Option A is incorrect because (int) only casts the returned String to an integer type without converting its value. Option B is incorrect because it attempts to cast a String to an Integer object without converting its value. Option D is incorrect because there is no Int.parseInteger() method in Java.
