两个for循环写出大小写字母表

public static void main(String[] args){int firstCapitalletter = (int)('A') - 1;int firstLowercaseLetter = (int)('a') -1;System.out.print("小写子母表");for(char i=1; i<26; i++){System.out.print((char)(firstCapitalletter+i) +" ");}System.out.println();System.out.print("大写子母表");for(char i=1; i<26; i++){System.out.print((char)(firstLowercaseLetter + i)+" ");}}
