如何显示图像和不同的变量取决于此代码中的某些条件？

Question

我正在学习 java，我对此还很陌生。我正在尝试使用 swing 创建静态配置文件 window。此外，头像图片应根据用户而变化，用户信息应从文本文件中读取。此代码没有给出错误，但它是因为 avatarPath。我认为该程序认为它是非静态的。

编辑：我稍微更改了代码，但出现错误。 Edit2：我想做的是创建用户和他们的个人资料。个人资料将包含头像图像和 3 个变量，即名称、姓氏和性别。我想针对用户显示它们。

我遇到了这些代码的问题；

static void AvatarPic(){ 
    if( x == 0 ){
    avatarPath = "\"/Users/hei_cosplay_darker_than_black_by_seras0victoria.jpg\"";
    }
    else if( x == 1 ){
    avatarPath = "\"/Users/lyralei_the_windrunner_by_trungth-d5zhmc1.jpg\"";    
    }
    else if( x == 2 ){
    avatarPath = "\"/Users/shingeki_no_kyojin_by_asuka10-d6k762k.jpg\""; 
    }
    }

和

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

Answer 1

你的代码有很多问题。

initComponents() 不是静态函数。我想在你的静态转换中你只是用 public 静态替换了每个函数。下面是一个构造函数 [I'我确定，因为它是 Netbeans 生成的] 并且您已经修改了它 also.No 需要这样做
```
 public static void ProfilePanel() {
   initComponents();
  }
```
您可以将其改回原来的样子
```
public ProfilePanel() {
  initComponents();
 }
```

您将在

获得 java.lang.NullPointerException

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

因为如果您使用 getResource you just have to specify the filename relative to the package.If you'll be loading from other location,then you have to change it like

jLabel1.setIcon(new javax.swing.ImageIcon(ProfilePanel.AvatarPic()));//file location

还必须给出绝对路径

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

您将在
再次获得 java.lang.NullPointerException
```
permitedUser[0] = new UsersInfo(s1[0], s1[1], s1[2]);
```
因为你还没有初始化 permitedUser anywhere.So 你必须这样做
```
static UsersInfo permitedUser[]=new UsersInfo[3];
```

进行这些更改后，如果您运行将其设置为 0，则 BK201[代号 Hei] 将出现在您的屏幕上

和您编辑的完整代码[更改 ImageLocations]
