*6.38（生成隨機(jī)字符）使用程序清單6-10RandomCharacter中的方法泄朴，打印100個大寫字母及100個一位數(shù)字蜻懦，每行打印10個。
*6.38(Generate random characters) Use the methods in RandomCharacter in Listing 6.10 to print 100 uppercase letters and then 100 single digits, printing ten per line.
下面是參考答案代碼:

public class Ans6_38_page205 {
public static void main(String[] args) {
for (int count = 1; count <=100; count++) {
System.out.print(getRandomUpperCaseLetter()+""+getRandomDigitCharacter());
if (count * 2 % 10 == 0)
System.out.println();
}
}
public static char getRandomCharacter(char ch1, char ch2) {
return (char)(ch1 + Math.random() * (ch2 - ch1 + 1));
}
/** Generate a random uppercase letter */
public static char getRandomUpperCaseLetter() {
return getRandomCharacter('A', 'Z');
}
/** Generate a random digit character */
public static char getRandomDigitCharacter() {
return getRandomCharacter('0', '9');
}
}
