What is the significance of keyset() method of MAP in Salesforce?

Hello shradha,

keyset() Returns a set that contains all of the keys in the map.

example:-

Map<String, String> colorCodes = new Map<String, String>();

colorCodes.put(‘Red’, ‘FF0000’);
colorCodes.put(‘Blue’, ‘0000A0’);

Set <String> colorSet = new Set<String>();
colorSet = colorCodes.keySet();

The above example will return the list of the keys i.e red and blue.

thanks.

In the field there is the following formula which checks the values in the picklist and text fields and returns 1 or 0 respectively:if ((Picklist__c = “Call Later” && CB__C = False), 1.0)What is wrong with this formula?
