法律研究Java程序计算句子中元音和辅音的个数
在本文中，我们将了解如何在Java中计算元音和辅音的个数。包括'a' 'e' 'i' 'o' 'u'的字母称为元音，所有其他字母称为辅音。
下面是演示：
输入
假设我们的输入是：
Hello, my name is Charlie
输出
期望的输出将是：
The number of vowels in the statement is: 8 The number of vowels in the Consonants is: 12
算法
Step1- Start Step 2- Declare two integers: vowels_count, consonants_count and a string my_str Step 3- Prompt the user to enter a string value/ define the string Step 4- Read the values Step 5- Run a for-loop, check each letter whether it is a consonant or an vowel. Increment the respective integer. Store the value. Step 6- Display the result Step 7- Stop
示例 1
这里，输入是根据提示由用户输入的。您可以在我们的代码练习工具 
中尝试此示例。
import java.util.Scanner;
public class VowelAndConsonents {
public static void main(String[] args) {
int vowels_count, consonants_count;
String my_str;
vowels_count = 0;
consonants_count = 0;
Scanner scanner = new Scanner(System.in);
System.out.println("A scanner object has been defined ");
System.out.print("Enter a statement: ");
my_str = scanner.nextLine();
my_str = my_str.toLowerCase();
for (int i = 0; i < my_str.length(); ++i) {
char ch = my_str.charAt(i);
if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u') {
++vowels_count;
}
else
if ((ch >= 'a' && ch <= 'z')) {
++consonants_count;
}
}
System.out.println("The number of vowels in the statement is: " + vowels_count);
System.out.println("The number of vowels in the Consonants is: " + consonants_count);
}
}输出
A scanner object has been defined Enter a statement: Hello, my name is Charlie The number of vowels in the statement is: 8 The number of vowels in the Consonants is: 12
示例 2
这里，整数已预先定义，并且其值在控制台上被访问和显示。
public class VowelAndConsonents {
public static void main(String[] args) {
int vowels_count, consonants_count;
vowels_count = 0;
consonants_count = 0;
String my_str = "Hello, my name is Charie";
System.out.println("The statement is defined as : " +my_str );
my_str = my_str.toLowerCase();
for (int i = 0; i < my_str.length(); ++i) {
char ch = my_str.charAt(i);
if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u') {
++vowels_count;
}
else
if ((ch >= 'a' && ch <= 'z')) {
++consonants_count;
}
}
System.out.println("The number of vowels in the statement is: " + vowels_count);
System.out.println("The number of vowels in the Consonants is: " + consonants_count);
}
}输出
The statement is defined as : Hello, my name is Charie The number of vowels in the statement is: 8 The number of vowels in the Consonants is: 11
