Rewrite code to handle printing text in a loop

I have a class that has some limited functionality. I'd like for it to be able to handle more related priorities without having to hard-code each scnario, e.g.:

 

List<Client_Priority__c> writePriority = new Client_Priority__c[6];
                   writePriority = [SELECT ClientCode__c, Priority_Notes__c, Status__c FROM Client_Priority__c
                                      WHERE Status__c = 'Active' AND Client_Priority__c.ClientCode__c =: cci.Id
                                      LIMIT 5];
                                       
                            //for(Client_Priority__c wp : writePriority){
                if(writePriority.size() == 1){
                                priorityList += 'Client Priorities: \r\n- ' + writePriority[0].Priority_Notes__c;
                                priorityList += '\r\n';
                }
                if(writePriority.size() == 2){
                                priorityList += 'Client Priorities: \r\n- ' + writePriority[0].Priority_Notes__c;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[1].Priority_Notes__c ;
                                priorityList += '\r\n';
                }
                if(writePriority.size() == 3){
                                priorityList += 'Client Priorities: \r\n- ' + writePriority[0].Priority_Notes__c;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[1].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[2].Priority_Notes__c ;
                }
                if(writePriority.size() >= 4){
                                priorityList += 'Client Priorities: \r\n- ' + writePriority[0].Priority_Notes__c;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[1].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[2].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[3].Priority_Notes__c ;
                }
                if(writePriority.size() >= 5){
                                priorityList += 'Client Priorities: \r\n- ' + writePriority[0].Priority_Notes__c;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[1].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[2].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[3].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[4].Priority_Notes__c ;
                }
                if(writePriority.size() >= 6){
                                priorityList += 'Client Priorities: \r\n- ' + writePriority[0].Priority_Notes__c;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[1].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[2].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[3].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[4].Priority_Notes__c ;
                                priorityList += '\r\n';
                                priorityList += '- ' + writePriority[5].Priority_Notes__c ;
                }

 

It prints text out too the client priorities field like this:

 

Client Priorities:

- A Priority

- Another Priority

- Foo Foo Foo

 

How could I get this to work in a loop to handle more than 6 (what I have coded for now) client priorities?

Here ya go, I hope this helps you.

String priorityList = '';
Integer num = 5;

List<Client_Priority__c> writePriority = new List<Client_Priority__c>();
writePriority = [SELECT ClientCode__c, Priority_Notes__c, Status__c FROM Client_Priority__c
    WHERE Status__c = 'Active' AND Client_Priority__c.ClientCode__c =: cci.Id
    LIMIT :num];

for (Integer i = 0; i < writePriority.size(); i++)
{
    if (i == 0)
    {
         priorityList += 'Client Priorities: \r\n- ' + writePriority[i].Priority_Notes__c;
    }
    else
    {
         priorityList += '- ' + writePriority[i].Priority_Notes__c ;
    }
    priorityList += '\r\n';  
}

Thanks, that definitely gave me some headway.

 

It writes out like this per your code:

 

Client Priorities:

- First priority

Client Priorities:

- Second priority

 

I revised it to look like this, which get's me 95% there. I just need to trim the last character, how do I do that?

 

This makes it look like this:

 

Client Priorities:

- blah blah

- more blah

-

 

I get an extra 'r\n- '. I just need to cut that off. 

 

Integer num = 10;
				
				List<Client_Priority__c> writePriority = new List<Client_Priority__c>();
				writePriority = [SELECT ClientCode__c, Priority_Notes__c, Status__c FROM Client_Priority__c
				    WHERE Status__c = 'Active' AND Client_Priority__c.ClientCode__c =: cci.Id
				    LIMIT :num];
				
                priorityList = 'Client Priorities: \r\n- ';
                
				for (Integer i = 0; i < writePriority.size(); i++)
				{
				    priorityList += writePriority[i].Priority_Notes__c;
				    priorityList += '\r\n- ';  
				}

Yeah, I edited my post right after you saw it probably. Look back up at my first post and try that again.

Works like a charm, thank you!
