编写一个Java程序,使用for循环打印从A到Z的字母。在这个Java例子中,for循环将从字母A到Z进行迭代,并将它们作为输出打印。
public class AlphabetsAtoZ {
public static void main(String\[\] args) {
char ch;
for(ch = 'A'; ch <= 'Z'; ch++) {
System.out.print(ch + " ");
}
}
这个Java程序遍历了从65到90的ASCII码,代表字母A到Z,并将其打印出来。在这里,我们用for循环、while循环和do while循环来向你展示各种可能性。
public class AlphabetsAtoZ2 {
public static void main(String\[\] args) {
for(int i = 65; i <= 90; i++)
{
System.out.printf("%c ", i);
}
System.out.println();
int j = 65;
while(j <= 90)
{
System.out.printf("%c ", j);
j++;
}
System.out.println();
int k = 65;
do
{
System.out.printf("%c ", k);
} while(++k <= 90);
}
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
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
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Java Alphabets from A to Z程序允许用户输入起始字母,并打印出其余的大写字母,直到Z。
import java.util.Scanner;
public class AlphabetsAtoZ3 {
private static Scanner sc;
public static void main(String\[\] args) {
char ch, strChar;
sc= new Scanner(System.in);
System.out.print("Please Enter any Character = ");
strChar = sc.next().charAt(0);
for(ch = strChar; ch <= 'Z'; ch++) {
System.out.print(ch + " ");
}
}
Please Enter any Character = G
G H I J K L M N O P Q R S T U V W X Y Z
