Code Explanation
As i already told we will use the SingleEmailMessage class of the Messaging Namespace. In Line number 1 we created object of the SingleEmailMessage class. In line number 2 we created a list of SingleEmailMessage because the sendEmail method only accepts List. In line number 3,4 and 5 we create variables to store the recipient email, subject and body respectively.
Now coming to line number 6,7 and 8 as i already told you earlier that SingleEmailMessage class has various methods which can be used to set various attributes so here we are setting recipient email address, subject and body.
In line number 8 we are adding the mail instance to the list which we have created. In Line number 9 we are sending the email using sendEmail. After that we are looping on the results variable and logging the results.
In this article we have seen how to send email using apex in Salesforce. We have covered few methods but you can check out list of all methods in the SingleEmailMessage class from here.
