Java"编写一个程序，根据用户输入的一个字符，判断字符是不是字母，如果是字母，判断该字母是声母换是韵母，是大写是小写字母，如果不是不是字母，则输出你输入的字符不是字母"求程序代码，用if或switch做

Answer 1

public static void main(String[] args) {

//小写声母
String[] ch1={"b","p","m","f","d","t","n","l","g","k","h","j","q","x","zh","ch","sh","r","z","c","s","y","w"};
//大写声母
String[] ch11={"B","P","M","F","D","T","N","L","G","K","H","J","Q","X","ZH","CH","SH","R","Z","C","S","Y","W"};

//小写韵母
String[] ch2={"a"," o", "e"," i", "u","v"};
//大写韵母
String[] ch22={"A"," O", "E","I", "U","V"};

Scanner sn=new Scanner(System.in);

while(true){

System.out.println("请输入：");
String str=sn.next();

boolean isWord=false;

for(int i=0;i<ch1.length;i++){
if(str.equals(ch1[i])){
System.out.println("小写声母："+str);
isWord=true;
break;
}
}
for(int i=0;i<ch11.length;i++){
if(str.equals(ch11[i])){
System.out.println("大写声母："+str);
isWord=true;
break;
}
}
for(int i=0;i<ch2.length;i++){
if(str.equals(ch2[i])){
System.out.println("小写韵母："+str);
isWord=true;
break;
}
}
for(int i=0;i<ch22.length;i++){
if(str.equals(ch22[i])){
System.out.println("大写韵母："+str);
isWord=true;
break;
}
}

if(! isWord){
System.out.println("不是字母"+str);
}

}
}

public class SwitchTest {

	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		while (true) {
			System.out.println("请输入一个字符");
			String line = input.next();
			if (line.length() > 1){
				continue;
			}
			char c = line.charAt(0);
			if (Character.isDigit(c))
				System.out.println(c + " 是数字");
			else if (Character.isAlphabetic(c)) {
				switch (c) {
				case 'a':
				case 'A':
				case 'e':
				case 'E':
				case 'i':
				case 'I':
				case 'o':
				case 'O':
				case 'u':
				case 'U':
					System.out.print(c + " 是韵母");break;
				default:
					System.out.print(c+" 是声母");
				
				}
				if (Character.isUpperCase(c))
					System.out.println(",也是大写字母");
				else
					System.out.println(",也是小写字母");
			}else
				System.out.println(c + " 是特殊字符");
		}
	}
