How do I count objects available in a Salesforce organization?

Question

I need to count the total number of custom objects available in a Salesforce organization. Is there a way to accomplish this?

Answer 1

You can easily do this using Global Describe

map<String, Schema.SObjectType> GlobalMap = Schema.getGlobalDescribe(); 
for (Schema.SObjectType Obj : GlobalMap.values()) {
    Schema.DescribeSObjectResult ObjDesc = Obj.getDescribe();
    system.debug('Object Name: ' + ObjDesc.getName());
}
System.debug(GlobalMap.size() );

Or if you want to see only custom objects then

Integer count = 0;
map<String, Schema.SObjectType> GlobalMap = Schema.getGlobalDescribe(); 
    for (Schema.SObjectType Obj : GlobalMap.values()) {
        Schema.DescribeSObjectResult ObjDesc = Obj.getDescribe();
        if(ObjDesc.iscustom()){
           count ++;
           system.debug('Object Name: ' + ObjDesc.getName());
        }
    }
System.debug('Custom Object '+ count );
