24. publicclass Hello { } Hello World public class Hello { public static void main(String[] args) { System.out.println("Hello world"); } } public Static void main(String[] args) { System.out.println("Hello world");

25. publicclass Hello { } Hello World public class Hello { public static void main(String[] args) { System.out.println("Hello world"); } } public Static void main(String[] args) { System.out.println("Hello world");

26. publicclass Hello { } Hello World public class Hello { public static void main(String[] args) { System.out.println("Hello world"); } } public Static void main(String[] args) { System.out.println("Hello world");

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

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

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

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