Example 3: Java Program to Check Alphabet using isAlphabetic() Methodclass Main { public static void main(String[] args) { // declare a variable char c = 'a'; // checks if c is an alphabet if (Character.isAlpha
publicclassCheckAlphabet{publicstaticvoidmain(String[]args){Stringstr="Hello World!";booleanhasLetter=false;for(inti=0;i<str.length();i++){charc=str.charAt(i);if(Character.isLetter(c)){hasLetter=true;break;}}if(hasLetter){System.out.println("The string contains letters.");}else{System....
使用Character类的isLetter方法: Character类提供了一个名为isLetter的方法,该方法可以判断给定的字符是否为字母(包括大写和小写)。 java public class CheckLetter { public static void main(String[] args) { char ch = 'A'; if (Character.isLetter(ch)) { System.out.println(ch + " is an alphabet....
使用Character类判断字符是否为英文字母 下面是使用Character类中的isLetter()方法来判断字符是否为英文字母的代码示例: publicclassCheckLetter{publicstaticvoidmain(String[]args){charch='A';if(Character.isLetter(ch)){System.out.println(ch+" is an alphabet.");}else{System.out.println(ch+" is not an...
the character (Unicode code point) to be tested. Returns Boolean trueif the character is a Unicode alphabet character,falseotherwise. Attributes RegisterAttribute Remarks Determines if the specified character (Unicode code point) is alphabetic.
Now, to check whether ch is vowel or not, we check if ch is any of: ('a', 'e', 'i', 'o', 'u'). This is done using a simple if..else statement. We can also check for vowel or consonant using a switch statement in Java. Example 2: Check whether an alphabet is vowel or...

string, we may wish to classify them according to whether they’re in a particular group. for example, characters in the english alphabet are either vowels or consonants. in this tutorial, we’ll look at a few methods to check if a character is a vowel. we could easily extend these ...
