I was trying to create a trigger where if there are 3 consecutive characters then it will not allow. But it is not working. Herewith I have attached my trigger:

public class TaskHandlerController {

public static void onBeforeInsert(List<Task> TaskList){

Set<String> taskID = new Set<String>();

for(Task a: TaskList){

    taskID.add(a.Id);

}

List<Task> updatePurpose = [SELECT Id, Purpose__c, Subject,Description FROM Task WHERE Id IN : taskID];

Map<String,Task> CommentMap = new Map<String,Task>();

for(Task a : updatePurpose){

    if(a.Description == 'aaa'){

        CommentMap.put(a.Description,a);

    }

}

for(Task a: TaskList){

    if(a.Description == 'aaa'){

        a.addError('Your custom error message');

    }

}

}

}

Can anyone help me with this?

There is something wrong in the code, you can try edit your trigger with the below statement.

if(Pattern.compile("(.)\\1{2}").matcher(a.Description).find()) { a.addError('Your custom error message'); }

I hope this will help.
