我正在尝试添加包级别注释,但我不知道如何做到这一点.赞赏的例子.
我一直在用JavaFx粉碎我的脑袋......
这适用于没有运行应用程序的实例的情况:
public class Runner {
public static void main(String[] args) {
anotherApp app = new anotherApp();
new Thread(app).start();
}
}
public class anotherApp extends Application implements Runnable {
@Override
public void start(Stage stage) {
}
@Override
public void run(){
launch();
}
}
但是,如果我new Thread(app).start() 在另一个应用程序中执行,我会得到一个例外,说明我不能进行两次启动.
此外,我的方法由另一个应用程序上的观察者调用,如下所示:
@Override
public void update(Observable o, Object arg) {
// new anotherApp().start(new Stage());
/* Not on FX application thread; exception */
// new Thread(new anotherApp()).start();
/* java.lang.IllegalStateException: Application launch must not be …例如,如果您有一个以制表符分隔的值列表:
foo1\tfoo2\tfoo3\tfoo4\t
最后\吨是由于自动追加添加\吨每+=.
你如何删除最后\ t在一个简单的方法？结果是:
foo1\tfoo2\tfoo3\tfoo4
作为Hover的请求,我的一个小例子:
String foo = "";
for (int i = 1; i <= 100; i++) {
foo += "foo" + "\t";
if (i % 10 == 0) {
foo = foo.trim(); // wasn't working
foo += "\n";
}
}
System.out.println(foo);
输出(替换为带有弦乐标签的实际标签,以便在此处显示):
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
foo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\tfoo\t
这就是我问这个问题的主要原因,.trim()不起作用,因此,我强调修剪()不是用于尾随标签.
我在哪里可以获得最新的jdk作为zip文件.我不想要jre,我想要完整的jdk.我无法运行exe甚至请求Windows安装程序,因此我无法下载.exe并运行它.此外,我无法访问一些上传网站,如Drop box或4shared.是否有任何ftp或地方我可以直接拉上jdk？非常感谢你.Jportable不够好,谢谢.
我想创建一些这样的加载点：
At 0 second the text on the screen is: Loading.
At 1 second the text on the screen is: Loading..
At 2 second the text on the screen is: Loading...
At 3 second the text on the screen is: Loading.
At 4 second the text on the screen is: Loading..
At 5 second the text on the screen is: Loading...
以此类推，直到我关闭了Stage。
用JavaFX做到最好/最简单的方法是什么？我一直在研究JavaFX中的动画/预加载器，但是在尝试实现这一点时似乎很复杂。
我一直试图在这三个之间创建一个循环Text：
Text dot = new Text("Loading.");
Text dotdot = new Text("Loading..");
Text dotdotdot …
