Java 程序检查字符是元音还是辅音

编写一个Java程序，使用if-else语句和一个示例来检查一个字符是元音还是辅音。If条件检查用户输入的字符是否是a、e、i、o、u、A、E、I、O、U。如果是，则是元音；否则，是辅音。

import java.util.Scanner;

public class CharVowelorConsonant1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		char ch;
		sc= new Scanner(System.in);

		System.out.print("Please Enter any Character =  ");
		ch = sc.next().charAt(0);
		
		if(ch == 'a' || ch == 'e' || ch == 'i' || ch <= 'o' || ch == 'u' ||
				ch == 'A' || ch == 'E' || ch == 'I' || ch <= 'O' || ch == 'U') 
		{
			System.out.println(ch + " is Vowel");
		}
		else 
		{
			System.out.println(ch + " is Consonant");
		}
	}
}

Java 程序使用 Switch Case 检查字符是元音还是辅音

请参考 If Else、Else If、Switch Case 和 ASCII Codes 来理解这个 Java 示例。

import java.util.Scanner;

public class Example2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		char ch;
		sc= new Scanner(System.in);

		System.out.print("\nPlease Enter any Character =  ");
		ch = sc.next().charAt(0);
		
		switch(ch) {
		case 'a':
		case 'e':
		case 'i':
		case 'o':
		case 'u':
		case 'A':
		case 'E':
		case 'I':
		case 'O':
		case 'U':
			System.out.println(ch + " is Vowel");
			break;
		default:
			System.out.println(ch + " is Consonant");	
		}
		
	}
}

Please Enter any Character =  g
g is Consonant

Please Enter any Character =  U
U is Vowel

在这个查找字符是元音还是辅音的程序示例中；首先，我们检查给定字符的ASCII值是否等于65、69、73、79、85、97、101、105、111或117。因为它们的ASCII码属于大写和小写元音。

如果为真，它将打印元音语句。接下来，我们查找字符是否在65到90或97到122之间，以检查辅音。

import java.util.Scanner;

public class Example3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		char ch;
		sc= new Scanner(System.in);

		System.out.print("\nPlease Enter any Char =  ");
		ch = sc.next().charAt(0);
		
		if(ch == 65 || ch == 69 || ch == 73 || ch == 79 || ch == 85 ||
				ch == 97 || ch == 101 || ch == 105 || ch == 111 || ch == 117) {
			System.out.println(ch + " is Vowel");
		}
		else if ((ch >= 65 && ch <= 90) || (ch >= 97 && ch <= 122)){
			System.out.println(ch + " is Consonant");
		}
		else {
			System.out.println("Please enter Valid Letter");
		}
	}
}

Please Enter any Char =  k
k is Consonant

Please Enter any Char =  9
Please enter Valid Letter

Please Enter any Char =  i
i is Vowel
