Posted by: xatm092 Posted on: 2007-05-19 13:47 我的做法是 (前面略,我想给出主要片段就行了.) System.out.println("1 A"); System.out.println("2 BB"); ...(中间略,我想你明白我的意思了.) System.out.println("26 ZZZZZZZZZZZZZZZZZZZZZZZZZZ"); System.out.println("27 012345678901234567890123456");

尝尝我ruby的厉害。

actual code.
<code>
n = ?A - 1
(1..26).each{|i| puts "#{i} #{(i+n).chr*i} "}
puts "27 " + (0..27).collect{|i| i%10}.to_s
</code>

some ruby explanation.
<code>
# some ruby language functions
#
# ?<X> return the ASCII code of the character
# ?A => 65
# ?B => 66
# ?\n => 10 backspace ASCII code is 10
#
#
# <N>.chr returns the character from given ASCII code
# 65.chr => "A"
# 66.chr => "B"
# 10.chr => "\n"
#
#
# <STR>*<n> multiplies given string n times.
# "ABC"*2 => ABCABC
#
#
# ruby use "#{var}" syntax to print variable in a string
# x = "abc"
# puts "output: #{x}" => "output: abc"
</code>

133xialiang 写得很不错，我也是初学java，向你学习。借鉴你的代码，我修改了一小下。不知道哪种写法执行效率更高些，请高人指点一下。

public class Test{
public static void main(String[] args) {
for (char c='A';c<='Z';c++){
for(int i=(int)'A'; i<=(int)c;i++){
System.out.print(c);

}
System.out.println();

}
for (int i=(int)'A'; i<=(int)'Z'+1;i++){
System.out.print((i-(int)'A')%10);
}

}

这个应该更合理些，打印函数forprint()可以完成很多其他
用途并且使得主函数看起来很简洁。

public class Test {

public static void main(String[] args) {
for (char c='A';c<='Z';c++){
forPrint(c,1);
System.out.println();

}
forPrint((char)((int)'Z'+1),2);

}

// 打印函数 forPrint()

public static void forPrint(char n ,int k){
for(char i='A'; i<=n;i++){

if(k==1){
System.out.print(n);
}else if(k==2){
System.out.print((i-'A')%10);
}
}

}

}
