How to remove particular key from a map?

This is pretty simple one, One of my friend asked me how to remove a particular key-value pair from a map.

Below is code snippet for the same. Hope It will help all.

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

colorCodes.put('Red', 'FF0000');
colorCodes.put('Blue', '0000A0');
colorCodes.put('Blue2', '0000A0');

// If you know the key then just use like below
System.debug('printing=== '+colorCodes);
//if you are not sure what about the key or need some manipulation then follow below approach
for(String key:colorCodes.keySet().clone()) {
    // myMap.get(key), process that value
System.debug('printing==ater= '+colorCodes);

How to get sandbox name in apex?

As we all know sandbox username looks like "behera@mycompany.com.dev "

dev- is the sandbox name, How can we get it this dynamically ?

Use below code :-

if(UserInfo.getUserName().substringAfterLast('.com')!= null)
                    contact.Email = contactInfo.Email+'.'+UserInfo.getUserName().substringAfterLast('.');
                    contact.Email = contactInfo.Email;

UserInfo.getUserName().substringAfterLast('.') - will give you sandbox name.

UserInfo.getUserName().substringAfterLast('.com') will tell you whether anything is there after " .com ". if not there that means we are in production otherwise in sandbox. 
We can also used same method to identify type of org like prod or non prod. There is another approach for this. 

Organization org = [select id,IsSandbox from Organization];
org.IsSandbox = true if it a sandbox. It willwork classs of higher version.

Feel free to suggest more.

Workaround for COMPILE ERROR: Field is not writeable: Account.IsPartner

As part of my requirement, I had to create an account making isPartner as true, Unfortunately I got this  COMPILE ERROR: Field is not writable: Account.IsPartner 

Then I first inserted that account then updated isPartner as true.

Account acc = new Account(name = 'Asish');
insert acc;
System.debug('Inserted account Ispartner ---'+acc.Ispartner);
acc.Ispartner = true;
update acc;
System.debug('Inserted account---'+acc);
