一本关于JBuilder 应用开发的书籍,希望大家喜欢,其实我没看过的,

public class HelloWorld
{
    private String helloMsg = "Hello World!";
    public static void main(String[] args)
    {
        HelloWorld hw = new HelloWorld();
     }
    public HelloWorld()
    {
    // 显示我们的"Hello World"消息
    System.out.println(helloMsg);
    }
}
