检查字符是元音还是辅音的Java程序

编写一个Java程序，使用if-else和一个例子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True，它是元音；否则，它是辅音。

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");
	}
}

使用Switch Case来检查一个字符是元音还是辅音的Java程序？

请参考If Else,Else If,Switch Case, 和ASCII码来理解这个Java例子。

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

在这个检查字符是元音还是辅音的Java程序例子中，首先，我们检查一个给定的字符的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、小写元音。如果是真的，它就会打印出元音语句。接下来，我们找出该字符是否在65到90之间或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
