I'm currently trying to go through all my code and make everyhing much more efficient..
Which means I'm trying to reduce the number of calls through statements etc.
I'm struggling to get my head around the MAP Class..
What I'm trying to do is Map All Accounts, but within my trigger I need to be able to call upon the specific account which matches Key__c from a custom object and return all account details.
I'm currently doing that with a query, but unsure how I can query a MAP to return results?
Zero Java experience and just currently trying to learn how to parse JSON from an API.
All the API call etc is fine, but it seems the more complex my JSON is the harder this is for me to wrap my head around.
I've managed to get a basic understanding and to get my current code to work with 2 API calls, but once I request a lot of details at once, there are multiple arrays and objects within that are causing me issue.
I've been using JSON2APEX which has helped a heap, but unsure if it is handling this complex request as its just not being logical in my head.
I've spent hours looking online and trying to understand before posting here..so any help would be greatly appreciated.
I'm currently able to get all the details to show and deserialize but I'm not sure then how to exactly split them into objects, for some reason only some work and not the other ones.
Code Below:
Public static void GetComments (String Key, String I) {
JSONParser parser = JSON.createParser(I);
while (parser.nextToken() != null)
{
if (parser.getCurrentToken() == JSONToken.START_ARRAY)
{
while (parser.nextToken() != null)
{
if (parser.getCurrentToken() == JSONToken.START_OBJECT)
{
GetComments.Issues j; GetComments.comment l;
try {
j = (GetComments.Issues)parser.readValueAs(GetComments.Issues.Class);
String s = JSON.serialize(j);
System.Debug('Serialized Projects: ' + s);
parser.skipChildren();
}
}
}
}
}
j then becomes:

Have removed any sensitive infromation but all data there is correct.
But when I have it as GetComments j = (GetComments)parser.readValueAs(GetComments.Class); it returns
