错误:应在名为 X.java 的文件中声明类 X 是公共的 [英] Error: class X is public should be declared in a file named X.java

问题描述

我正在尝试编写一个程序，但我收到此编译器错误:

I am trying to write a program, but I'm getting this compiler error:

Main.java:1: error: class WeatherArray is public, should be declared in a file named WeatherArray.java
public class WeatherArray {
       ^
1 error

我检查了我的文件名，我的公共类与我的 .java 文件相同.

I have checked my file names, and my public class is the same as my .java file.

我该如何解决这个问题?

How can I fix this?

这是我的代码:

public class WeatherArray {
    public static void main(String[] args) {
        // ...
    }
}

推荐答案

公共类的名称必须与放置它的 .java 文件的名称相匹配(例如 public class Foo{} 必须放在 Foo.java 文件中).所以要么:

Name of public class must match the name of .java file in which it is placed (like public class Foo{} must be placed in Foo.java file). So either:

• 将您的文件从Main.java重命名为WeatherArray.java
• 将 class 从 public class WeatherArray { 重命名为 public class Main {

• rename your file from Main.java to WeatherArray.java
• rename the class from public class WeatherArray { to public class Main {
