[SalesForce] Method does not exist or incorrect signature: void put(String, String) from the type Map>

Below code throws this error:

Method does not exist or incorrect signature: void put(String, String) from the type Map<String,Map<String,String>>

Code:

//I have this map
Map <String,Map <String,String>> MapFist= new Map <String,Map<String,String>>();

//I need the popular map with these values

MapFist.put('FiestIndex', 'SecondIndex','Value');

You need to access each nested map level individually. Always make sure you initialize the inner layers before you attempt to use them (or you'll get a NullPointerException).

MapFist.put('FiestIndex', new Map<String, String>());
MapFist.get('FiestIndex').put('SecondIndex', 'Value');

[SalesForce] Method does not exist or incorrect signature: [Id].contains(String)

Id objects don't contain all the same methods as String objects. Cast one into the other first.

You could change your example to ((String)cpnCod.Account_name__c).contains(quoteStr)

[SalesForce] Method does not exist or incorrect signature: [String].put(String)

The problem is not while you are retrieving; it's when you are assigning the value.

ownerIdstoNames.get(owner.Id).put(owner.Name); // Method does not exist or incorrect signature: [String].put(String)

Lets break this into two steps:

ownerIdstoNames.get(owner.Id)

This will return a String because you have a map
String.put(owner.Name)

There is no string method called put .Map has a put method but not String .

Instead just use put on the map and because the key of the map is unique ,your key will have correct value assigned
```
for (User owner: owners) {
    ownerIdstoNames.put(owner.Id,owner.Name); //Put into the map
}
```
