Error in code: <identifier>expected

[Gnapika]

public class HelloWorldBean implements HelloWorld 
{
    public void sayHello(String name); 
            System.out.println("Hello, World");
}

This is the code i want to execute but it is showing an error like <identifier>expected..

You need to specify where the function begins and ends with curly brackets.

public class HelloWorldBean implements HelloWorld  
{ 
    public void sayHello(String name)
   { 
            System.out.println("Hello, World");
    }
}

Hi! you have to start and close the curly brackets from where your function starts and you put a semicolon after function which is not allowed.

    public class HelloWorldBean implements HelloWorld  
    { 
        public void sayHello(String name)
       { 
                System.out.println("Hello, World");
        }
    }
