Not a statement java ошибка что значит

I am new to java programming. I tried hello world program, but I got an error «not a statement«. Whereas when I copy, paste the hello world program from the internet, my program compiled. This is the program I used. What is meant by «not a statement«, please explain why I got this error and what is meant by it and what should I look for when I get this error in the future. Thanks!

public class hello
{
    public static void main(String args[]) {    
        System.out.println(“hello world”);
    }
}

My errors:-

hello.java:8: error: illegal character: 'u201c'
       System.out.println(“hello world”);
                          ^
hello.java:8: error: ';' expected
       System.out.println(“hello world”);
                           ^
hello.java:8: error: illegal character: 'u201d'
       System.out.println(“hello world”);
                                         ^
hello.java:8: error: not a statement
       System.out.println(“hello world”);
                                 ^
4 errors

You code cannot contain smart quotes like your used in your «Hello World». I replaced your smart/fancy quotes with the correct kind.

public class hello
{
    public static void main(String args[]) {    
        System.out.println("hello world");
    }
}

Hi I am new to java programming. I want to write a java program that gets the first name and the surname initials of the user. My code is:

public class MyProgram {
public void start() {
    String name = getNameFromUser();
    char firstNameInitials = getInitials(name);
    char surnameInitials = getInitials(name);
    printInitials(firstNameInitials, surnameInitials);
}
private String getNameFromUser() {
    System.out.print("Please enter your name: ");
    String name = Keyboard.readInput();
    return name;
}
private char getInitials(String name) {
    char firstNameInitials = name.charAt(0);
    int indexOfSpace = name.indexOf(" ");
    char surnameInitials = name.charAt(indexOfSpace + 1);

    return firstNameInitials; surnameInitials;
}

private void printInitials(String firstNameInitials, String surnameInitials){
    System.out.print("your initials are: " + firstNameInitials +". " + surnameInitials +".");
}
}

i am getting an error message, i dont know what it means:

Error: not a statement.

The error seems to be at line 18, at the return statement.
I have tried to fix it but have failed. Any suggestions how can I fix this please?

error:

return firstNameInitials; surnameInitials;

return only one value;

 printInitials(firstNameInitials, surnameInitials);

either convert the function to take char as parameter or change the arguments to string.

Please try this. You made some simple mistakes.

public class Testprg
{
   public void start()
   {
    String name = getNameFromUser();
    char firstNameInitials = getFirstNameInitials(name);
    char surnameInitials = getSurNameInitials(name);
    printInitials(firstNameInitials, surnameInitials);
   }

   private String getNameFromUser()
   {
    System.out.print("Please enter your name: ");
    String name = Keyboard.readInput();
    return name;
   }

   private char getFirstNameInitials(String name)
   {
    char firstNameInitials = name.charAt(0);

    return firstNameInitials;
   }

   private char getSurNameInitials(String name)
   {
    int indexOfSpace = name.indexOf(" ");
    char surnameInitials = name.charAt(indexOfSpace + 1);

    return surnameInitials;
   }

   private void printInitials(char firstNameInitials, char surnameInitials)
   {
    System.out.print("your initials are: " + firstNameInitials + ". " + surnameInitials + ".");
   }
}
