使用Regex检查字符串在Java中是否仅包含字母
首先,将字符串转换为字符数组。在这里,名称 是我们的字符串-
char[] ch = name.toCharArray();
现在,遍历并查找字符串是否仅包含字母。在这里,我们正在检查字符串中每个字符的字母是否均不等于字母-
for (char c : ch) { if(!Character.isLetter(c)) { return false; }
以下是使用正则表达式检查字符串是否仅包含字母的示例
示例
public class Main { public static boolean checkAlphabet(String name) { char[] ch = name.toCharArray(); for (char c : ch) { if(!Character.isLetter(c)) { return false; } } return true; } //主要方法 public static void main(String[] args) { String str1 = "Tom1"; System.out.println("String1 = " + str1); System.out.println("Does String1 contains only alphabets? = " + checkAlphabet(str1)); String str2 = "Tim"; System.out.println("String2 = " + str2); System.out.println("Does String2 contains only alphabets? = " + checkAlphabet(str2)); } }
输出结果
String1 = Tom1 Does String1 contains only alphabets? = false String2 = Tim Does String2 contains only alphabets? = true
