Answer 1

你可以把大写的 封装成一个字符串 小写的封装成一个字符串 再分别输出这两个字符串即可

望采纳~~~~~~~~~~~~

Answer 2

public class Ex2_1 {
public static void main(String[] args) {
for(int i=0;i<=26;i++)
System.out.print((char)('Z' - i) + " ");
System.out.println();
for(int i=0;i<=26;i++)
System.out.print((char)('z' - i) + " ");}

Answer 3

只能写两个循环了。

for(int i=0;i<=26;i++){ 
 System.out.print((char)('Z' - i) + " "); 
} 
System.out.println("");
for(int i=0;i<=26;i++){ 
 System.out.print((char)('z' - i) + " ");
}

Answer 4

for (int i = 0; i <= 26; i++) {
System.out.print((char) ('Z' - i) + " ");
}
System.out.println();
for (int i = 0; i <= 26; i++) {
System.out.print((char) ('z' - i) + " ");
}

Answer 5

for (char i = 'a'; i <= 'z'; i++) {
System.out.print(i+" ");
// System.out.println(i+" ".toUpperCase());
}
System.out.println();
for (char i = 'A'; i <= 'Z'; i++) {
System.out.print(i+" ");

}
