Java程序查找给定字符是否为字母
从用户读取一个字符，以验证它是否位于a和z之间（小写和大写）。如果是，则为字母。
示例
import java.util.Scanner;
public class AlphabetOrNot {
public static void main(String args[]){
System.out.println("Enter a character :: ");
Scanner sc = new Scanner(System.in);
char ch = sc.next().charAt(0);
if(((ch >= 'A' && ch <= 'Z')||ch >= 'a' && ch <= 'z') ){
System.out.println("Given character is an alphabet");
}else{
System.out.println("Given character is not an alphabet");
}
}
}输出结果
Enter a character :: d Given character is an alphabet
