/*
Syntax of defining java class is,
 
    <modifier> class <class-name>{
    
    // members and methods
    
    }
*/
 
public class JavaClassExample{
    
    /*
    Syntax of defining members of the java class is,
        <modifier> type <name>;
    */
    
    private String name;
    
    /*
    Syntax of defining methods of the java class is,
    
        <modifier> <return-type> methodName(<optional-parameter-list>) <exception-list>{
            ...
        }
    */
    
    public void setName(String n){
        //set passed parameter as name
        name = n;
    }
    
    public String getName(){
        //return the set name
        return name;
    }
    
    //main method will be called first when program is executed
    public static void main(String args[]){
    
        /*
        Syntax of java object creation is,
            <class-name> object-name = new <class-constructor>;
        */
       
        JavaClassExample javaClassExample = new JavaClassExample();
       
        //set name member of this object
        javaClassExample.setName("Visitor");
       
        // print the name
        System.out.println("Hello " + javaClassExample.getName());      
    
    }
 
}
