Getting error “Error: Could not find or load main class A Caused by: java.lang.ClassNotFoundException: A” in MAC OSX

Question

MAC OSX

I have the java source file A.java in "$HOME/Documents/personal_documents/java".

class A
{
 public static void main(String args[])
 {

 }
}

Executed following commands:-

1. cd $HOME/Documents/personal_documents/java
2. javac A.java ('Got successfully executed')
3. java A ('Threw the error': Error: Could not find or load main class A , Caused by: java.lang.ClassNotFoundException: A)

Troubleshooting I did on my part:-

1. /usr/libexec/java_home

   /Users/rishabshinghal/Library/Java/JavaVirtualMachines/openjdk-14.0.1/Contents/Home

2. Tried setting JAVA_HOME, PATH env variables explicitly.

   export PATH=$PATH:$HOME/Library/Java/JavaVirtualMachines/openjdk-14.0.1/Contents/Home/bin

   export JAVA_HOME=$(/usr/libexec/java_home)

3. Tried executing javac, java using absolute paths

   $HOME/Library/Java/JavaVirtualMachines/openjdk-14.0.1/Contents/Home/bin/javac A.java

   $HOME/Library/Java/JavaVirtualMachines/openjdk-14.0.1/Contents/Home/bin/java A

4. Also tried setting classpath explicitly even though I am in the same directory as class file.

   javac A.java

   java -cp . A

Please help me in this. I spent lot of time in troubleshooting this but didn't get any breakthrough.
