晚上好，我仍然對我的項目工作（試圖更加努力提高自己。）設置X犯規的頻率會影響我的整個程序
我有一個轉換的錢到另一個貨幣型（如歐元美元計劃），我有我的菜單，我正在設定自己的費率。它設定的速度非常好，但當我嘗試轉換貨幣時，setRate不影響它，結果是NaN或無窮大。這是我的整個代碼。
private JMenuBar menuBar = new JMenuBar(); // Window menu bar
public Converter(String title) {
setTitle(title);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setJMenuBar(menuBar); // Add the menu bar to the window
JMenu fileMenu = new JMenu("File"); // Create File menu
JMenu elementMenu = new JMenu("Rate Setters"); // Create Elements menu
JMenuItem subTest = new JMenuItem("Test");
JMenuItem rateMyMoney = new JMenuItem("Set the Rates.");
subTest.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
Converter convert = new Converter();
GridLayout converterGridLayout = new GridLayout(2,2,12,6);
convert.setLayout(converterGridLayout);
convert.setVisible(true);
}
});
rateMyMoney.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
SetMyRates setRates = new SetMyRates();
GridLayout setRateGridLayout = new GridLayout(2,2,12,6);
setRates.setLayout(setRateGridLayout);
setRates.setVisible(true);

menuBar.add(fileMenu); // Add the file menu
menuBar.add(elementMenu); // Add the element menu
fileMenu.add(subTest);
elementMenu.add(rateMyMoney);

爲什麼犯規setRate犯規影響的代碼時，我嘗試將其轉換？
您確實需要包含更少的代碼。讓它更多[sscce]（http://sscce.org/）。告訴我們你到底發生了什麼錯誤或者哪裏出了問題。 – MarioDS
一切工作正常，重點是，我有我的主菜單上的2個子菜單是轉換器，另一個是SetRates。設置費率從文本字段中讀取整數並將其設置爲我的money.java上的setRate，例如我將美元的比率設置爲2，並打開我的Converter子菜單，作爲輸入，我寫了3，所以它應該做的是2/3將其轉換爲歐元，但它不能識別3當我打開轉換子菜單：/ –
然後要麼它工作不正常或其他錯誤...就像我說的，是否發生錯誤？你有沒有調試代碼？ – MarioDS
