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
