12. Java Programming: From Problem Analysis to Program Design, 5e To simplify the use of (public) static methods of a class, Java 5.0 introduces the following import statements: These are called static import statements. After including such statements in your program, when you use a (public) static method (or any other public static member) of a class, you can omit the name of the class and the dot operator.
21. Equivalent Method Definitions Java Programming: From Problem Analysis to Program Design, 5e public static double larger( double x, double y) { double max; if (x >= y) max = x; else max = y; return max; }

28. Solution: isPalindrome Method Java Programming: From Problem Analysis to Program Design, 5e public static boolean isPalindrome(String str) { int len = str.length(); int i, j; j = len - 1; for (i = 0; i <= (len - 1) / 2; i++) { if (str.charAt(i) != str.charAt(j)) return false ; j--; } return true ; }

31. Solution: Largest Number Java Programming: From Problem Analysis to Program Design, 5e static Scanner console = new Scanner(System.in); public static void main(String[] args) { double num; double max; int count; System.out.println("Enter 10 numbers."); num = console.nextDouble(); max = num; for (count = 1; count < 10; count++) { num = console.nextDouble(); max = larger(max, num); } System.out.println("The largest number is " + max); }
