类存在，但说"java.lang.ClassNotFoundException"

Question

我试图在macOS终端上编译和运行一个基本的hello word java程序，它成功编译，但当我运行它时，它说java.lang.ClassNotFoundException: Main。

Hello.java

class Main {
public static void main(String[] args) {
System.out.println("hello");
}
}

~/. zshrc

export PATH=/usr/local/opt/openjdk/bin:$PATH
export CLASSPATH=$PWD/activation-1.1.jar:/usr/local/opt/openjdk/plugins/javax.mail.jar

终端

arghadip@Mac % rm *.class; ls; javac Hello.java; ls; java Main;
Hello.java
Hello.java  Main.class
Error: Could not find or load main class Main
Caused by: java.lang.ClassNotFoundException: Main
arghadip@Mac % 

我已经安装了java与brew install java。出了什么问题?

Answer 1

不尝试运行Main.class

just do:java Hello.java
