Java 如何显示图像和不同的变量取决于此代码中的某些条件？

我正在学习java，我对它很陌生。我正在尝试使用swing创建一个静态配置文件窗口。此外，化身图片应当根据用户而改变，并且应当从文本文件读取用户信息。此代码未给出错误，但其原因是

avatarPath

。我认为程序认为它是非静态的

代码中有很多问题

initComponents（）

不是一个静态函数。我猜在静态转换中，您只是用公共静态替换了每个函数。下面是一个构造函数[我确定，因为它是一个

Netbeans

生成的构造函数]，您也对它进行了修改。无需这样做

 public static void ProfilePanel() {
   initComponents();
  }

你可以把它改回原来的样子

public ProfilePanel() {
  initComponents();
 }

您将在

jLabel1.setIcon(new javax.swing.ImageIcon(getClass().getResource(ProfilePanel.AvatarPic())));

permitedUser[0] = new UsersInfo(s1[0], s1[1], s1[2]);

因为如果使用，只需指定与包相关的文件名。如果要从其他位置加载，则必须更改它

还必须给出绝对路径

avatarPath = "D://hei_cosplay_darker_than_black_by_seras0victoria.jpg";

您将再次在中获得

java.lang.NullPointerException

jLabel1.setIcon(new javax.swing.ImageIcon(getClass().getResource(ProfilePanel.AvatarPic())));

permitedUser[0] = new UsersInfo(s1[0], s1[1], s1[2]);

因为您没有在任何地方初始化

permitedUser

，所以您必须像

static UsersInfo permitedUser[]=new UsersInfo[3];

进行这些更改后，如果您使用0运行它，那么BK201[代码名Hei]将出现在您的屏幕上

和您编辑的完整代码[更改图像位置]
