编写一个Java程序,使用for循环、while循环和do-while循环显示从a到z的字母。在这个例子中,所有循环都从字母a迭代到z并显示它们作为输出。
public class Alphabetsatoz1 {
public static void main(String[] args) {
char lwch;
for(lwch = 'a'; lwch <= 'z'; lwch++)
{
System.out.print(lwch + " ");
}
System.out.println();
char lwch1 = 'a';
while (lwch1 <= 'z')
{
System.out.print(lwch1 + " ");
lwch1++;
}
System.out.println();
char lwch2 = 'a';
do
{
System.out.print(lwch2 + " ");
} while (++lwch2 <= 'z');
}
}

这个程序显示从a到z的字母,它迭代ASCII码从97到122,分别代表字母a到z,并打印它们。
public class Example2 {
public static void main(String[] args) {
for(int i = 97; i <= 122; i++)
{
System.out.printf("%c ", i);
}
}
}
a b c d e f g h i j k l m n o p q r s t u v w x y z
这个显示从a到z的字母的程序允许用户输入开始的小写字母,并打印到z的其余字母。
import java.util.Scanner;
public class Example3 {
private static Scanner sc;
public static void main(String[] args) {
char ch, strlwChar;
sc= new Scanner(System.in);
System.out.print("Please Enter any Char = ");
strlwChar = sc.next().charAt(0);
for(ch = strlwChar; ch <= 'z'; ch++) {
System.out.print(ch + " ");
}
}
}
Please Enter any Char = h
h i j k l m n o p q r s t u v w x y z
