Solution to Recognizing Errors

2.
Hello.java:7: class Helo is public, should be declared in a file named Helo.javapublic class Helo
       ^
1 error

3. There is no error message because a string is not an identifier -- it can
contain any characters.  The program now prints Helo instead of Hello.

4. 
Hello.java:14: unclosed string literal
        System.out.println ("Hello, World!);
                            ^
Hello.java:14: ')' expected
        System.out.println ("Hello, World!);
                                            ^
2 errors

5. There were 5 errors, but they weren't very helpful in determining that
the first " was missing.

6. 
Hello.java:14: ';' expected
        System.out.println ("Hello, World!")
                                            ^
1 error
