接下来我们开始创建java project,注意我们暂时只使用java project 而不是maven 我们在弹出的窗口中输入项目名称 swing_helloworld,使用默认的jdk17,点击next继续 这里进行java项目的build设置,就是项目创建完成后,我们在项目右键属性的java build界面,我们这里直接点击finish 项目创建完成后的主
5 向窗口中增加面板,增加lable:JPanel panel = new JPanel();mainFrame.add(panel); JLabel userLabel = new JLabel("hello world"); userLabel.setBounds(20,30,80,25); panel.add(userLabel);6 设置窗口可见。mainFrame.setVisible(true);7 运行程序,弹出窗口 hello world。完成第一个java swing程序。

public class HelloWorld { /* 第一个Java程序 * 它将输出字符串 Hello World */ public static void main(String[] args) { System.out.println("Hello World"); // 输出 Hello World } } 下面将逐步介绍如何保存、编译以及运行这个程序: 打开代码编辑器,把上面的代码添加进去; 把文件名保存为:HelloWorld...

4、JavaFX 仍然可以使用 Swing 程序,通过SwingNode即可 5、原来开发 JavaFX 程序,需要单独下载 JavaFX 的SDK,但是现在不需要了。从 JDK 7u6 开始,JavaFX 被内置到 Java SE中;从Java8开始,JavaFX 版本更新为JavaFX8。现在开发Java FX程序可以像以前开发awt、swing一样直接进行开发 ...
This program compiles in JDK 6 - inferringIntegerfor the type-variable Z. Now, if you replace Integer for Z in the declaration of 'm' [this leads tom(List<? super Integer>)], it is easy to spot that the method should not be applicable, as we are attempting to pass aList<? super...
