Not able to execute the program.

[Joy Vergis]

I am able to compile the below program but not able to execute.

public class String {
   public static void main(String[] agrs){
  System.out.println("Hello String");
    }
}

Output Error:

Class String does not have a main method

Here's a good lesson. Don't give your classes the same name as existing classes in the standard Java API, or at least the java.lang and java.util packages.

What's the type of agrs? It's an array of String, but not java.lang.String.

Don't use String for your class name. It is already taken by java.lang.String.

When you execute java String from the command line, JVM first looks for classes in JDK. It finds java.lang.String and it tries to execute its main method.
The class java.lang.String does not have one thus the error.
This is wrong. Stephan van Hulst gave a correct explanation.

Change your class name to something else.

And you see, it adversely affected your other program.
