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

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

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

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

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

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

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