Check if a string contains only alphabets in Java using Regex

At first, convert the string into character array. Here, name is our string −

char[] ch = name.toCharArray();

Now, loop through and find whether the string contains only alphabets or not. Here, we are checking for not equal to a letter for every character in the string −

for (char c : ch) {    if(!Character.isLetter(c)) {       return false;    }

Following is an example to check if a string contains only alphabets using Regex

Example

 Live Demo

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;    }    // Main method    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));    } }

Output

String1 = Tom1 Does String1 contains only alphabets? = false String2 = Tim Does String2 contains only alphabets? = true
