How to check for code coverage in apex?

What does apexcodecoverageaggregate do for a class?

ApexCodeCoverageAggregate stores the sum of covered lines for a class after checking all test methods that test it. ApexCodeCoverage stores the lines that are covered and uncovered by each individual test method. For this reason, a class can have multiple coverage results in ApexCodeCoverage—one for each test method that has tested it.
