Split the comma separated values and check length of each value

Hi All,

I have a requirement where the field holds comma separated values. Let's say 1234,4567,7890 like this. I want to split these values and check each value length. If length is <4 then error message should be displayed to user. Please help me how to achive this. I know that i should use split method first but after that how to check each field length?

Your inputs appreciated.

Thanks.

You can create a method in a class passing the string. Here is the code for you. You can change the classname or add the method in any of your existing class
  
public class StringFunctions {

    Public class wrongLengthException extends Exception {}

    public static  void StringLengthCheck(String strValue) {
    
    String[] strArray = strValue.Split(',');
    
        for(String str : strArray) {
            
             If (str.length() < 4)
                  Throw new wrongLengthException ( 'Incorrect length value found');
        }
    }
}

You can use the method as follows 
try {
    StringFunctions.StringLengthCheck('1234,5678,912');
} catch (Exception ex) {
    system.debug(ex.getMessage());
}

Public class wrongLengthException extends Exception {}

String strValue = ‘1234,3456,334’;
String[] strArray = sreValue.Split(‘,’);

for(String str : strArray) {
    
     If (str.length() < 4)
          Throw new wrongLengthException ( ‘Incorrect length value found’);
}

I hope this help

Hi All,

Could someone pleasehelp me further on this. I need to display error message if user enters field value as 1234,5678,912 and trying to save record. Logic should check each value before comma and check legth of it. I need this to be executed in before insert and update.

Thanks.

String strValue = '1234,5678,912';
String[] strArray = strValue.Split(',');

for(String str : strArray) {
if(str=='1234'){
System.debug('error');
}
else if(str=='5678'){
System.debug('error');
}
else if(str=='912'){
System.debug('error');
}else {
System.debug('NO error');
}
}
