how check if String has Full width character in java

Question

Can anyone suggest me how to check if a String contains full width characters in Java? Characters having full width are special characters.

Answer 1

You can compare the UNICODE Since unicode for alphabets (a-z) is 97-122 , So you can easily diffrentiate between the two

String str="ａｂｃ＠ｇｍａｉｌ.ｃｏｍ";
System.out.println((int)str.charAt(0));

for Input

ａｂｃ＠ｇｍａｉｌ.ｃｏｍ

Output

65345
