1. 程式設計實作

2. 實作 實作一 實作二 (Palindrome integer) Write the following two methods
// Return the reversal of an integer, i.e. reverse(456) returns 654
public static int reverse(int number)
// Return true if number is palindrome
public static boolean isPalindrome(int number)
Use the reverse method to implement isPalindrome. A number is a palindrome
if its reversal is the same as itself. Write a test program that prompts the
user to enter an integer and reports whether the integer is a palindrome.
實作二
(Using the Random class) Write a program that creates a
Random object with seed1000 and displays the first 50 random integers
between 0 and 100 using the nextInt(100) method.

3. 實作
實作三
(Binary to hex) Write a method that parses a binary number into a hex number.
The method header is as follows:
public static String binaryToHex(String binaryValue)
Write a test program that prompts the user to enter a binary number and displays
the corresponding hexadecimal value.
實作四
(Displaying labels) Write a program that displays four lines of text in four
labels, as shown in Figure 12.15(a). Add a line border on each label.
