Error in program

[jose chiramal]

  
class ThrowDemo {
	static void demoproc()
	{
	try
	{
		throw new Throwable ("th");
	}
	
	catch (Throwable th)
	{
		System.out.println("hello from catch of throwables");
	}
	 
	public static void main( String args[]){
	demoproc();
	}
	}
}

it gives me an error : java.lang.NoSuchMethodError: main
Exception in thread "main" . Anything wrong ?

Edited again: Please use code tags only for the code, not expository text.

First of all: What kind of difficulties / error are we talking about. Is it a compiler error, or an error at runtime?
Second: Use code tags
Third: Check your blocks / braces. I think there's one closing bracket missing.

// Edit. OK, forget about the code tags ; - )

You have your main method inside of your demoproc() method. I'm not sure you can do that.

[Devaka Cooray]

I'm not sure you can do that.

Yep, you cannot.

Ps - Indenting the code properly makes the life easy.

[fred rosenberger]

here is your code properly formatted:

 
class ThrowDemo 
{
   static void demoproc()
   {
      try
      {
         throw new Throwable ("th");
      }
      catch (Throwable th)
      {
         System.out.println("hello from catch of throwables");
      }
      
      public static void main( String args[])
      {
         demoproc();
      }
   }
}
   

From that, it's easy to see you have a method (main) defined inside the demoproc method. You can't do that. Methods cannot be nested inside each other in java.

It is well worth the effort to pay attention to proper indenting.
If you do, this kind of problem just does not happen.
