Swing：从两个私有jTextField？ActionPerformed类中获取变量

我在NetBeans 8.2中，我为二进制到十进制转换器构建了一个很好的jFrame GUI，我想我的两个文本字段中的代码是正确的，但我无法弄清楚如何访问我的变量用于执行操作的按钮。

我有3个方法操作，称为parseBinary，isBinary和非法，我想用它来对我的两个文本字段执行操作。 在NetBeans中，当您对按钮进行编码时，该方法将被锁定为私有，因此这是我的问题。

我将发布我的所有代码并突出显示我的问题（靠近底部）：

import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.util.Scanner; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; public class Assignment2_gui extends javax.swing.JFrame { public static int parseBinary(String binary) throws NumberFormatException { if (!isBinary(binary)) { throw new NumberFormatException("Invalid Format for a Binary String - Illegal character: " + illegal(binary)); } int power = 0; int decimal = 0; for (int i = binary.length() - 1; i >= 0; i--) { if (binary.charAt(i) == '1') { decimal += Math.pow(2, power); } power++; } return decimal; } public static boolean isBinary(String binary) { for (char ch : binary.toCharArray()) { if (ch != '1' && ch != '0') { return false; } } return true; } public static char illegal(String iChar) { char test = 0; char arr[] = iChar.toCharArray(); for(char cha : arr) { if (cha != '1' && cha != '0') { test = cha; } } return test; } /** * Creates new form Assignment2_gui */ public Assignment2_gui() { initComponents(); } /** * This method is called from within the constructor to initialize the form. * WARNING: Do NOT modify this code.
