Example 2: Java Program to Check Alphabet using ternary operatorpublic class Alphabet { public static void main(String[] args) { char c = 'A'; String output = (c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z') ? c + " is an alphabet." : c + " is not an ...
下面是使用正则表达式判断字符是否为英文字母的代码示例: publicclassCheckLetter{publicstaticvoidmain(String[]args){charch='1';if(Character.toString(ch).matches("[a-zA-Z]")){System.out.println(ch+" is an alphabet.");}else{System.out.println(ch+" is not an alphabet.");}}} 1. 2. 3. ...
另外,我们还可以使用Character类中的isLetter()方法来进行判断: importjava.util.Scanner;publicclassCheckAlphabet{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);System.out.println("请输入一个字符:");charinput=scanner.next().charAt(0);if(Character.isLetter(input)){System.out.p...
Example 1: Check whether an alphabet is vowel or consonant using if..else statement public class VowelConsonant { public static void main(String[] args) { char ch = 'i'; if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ) System.out.println(ch ...
Char #2Char !3Char @3Char $2Char %2 参考: HashMap java 程序:使用Stack,Queue,for或while循环检查回文串 原文:https://beginnersbook.com/2014/01/java-program-to-check-palindrome-string/ 在本教程中,我们将看到程序来检查给定的String是否是回文。以下是实现目标的方法。
privatestaticfinalchar[]ALPHABET="abcdefghijklmnopqrstuvwxyz".toCharArray(); publicstaticvoidmain(String[] args)throwsException { newSpellCheck().start(); } publicvoidstart()throwsIOException { // 1.Build language model Map<String, Double> langModel = buildLanguageModel("big.txt"); ...
that condition will always return False. one way to do it is : check the first char in str and see if it is lower or uppercase then check the rest based on the first status. if they are all the same case return True otherwise false. ...
