first-class load的意思|示意

Because the parent class loader is always given the opportunity to load a class first, the class is loaded by the class loader nearest the root.

因为父类类装入器总是先得到装入类的机会，所以类装入器装入的类最靠近根。

Every class loader has a parent class loader, which delegates the searching and loading of a class to its parent (parent-first delegation) before it attempts to load the class itself.

每个类加载器有一个父类加载器，在尝试加载类本身时，先将类搜索和类加载委托给它的父加载器，即父加载器优先（parent-first）委托。

The First time value is the time taken for constructing the first reflection replacement class, which includes the time to load and initialize the classes in the framework code.

第一个时间值是构建第一个反射替代类所花费的时间，这个时间包括装载和初始化框架代码中的类的时间。

For example, a class loader could first load a class explicitly and then load all of its referenced classes implicitly.

例如，类装入器可能先显式地装入一个类，然后再隐式地装入它引用的所有类。

Note that class loading can be performed in a lazy manner and therefore some parts of the class loading process may be done on first use of the class rather than at load time.

请注意可以用惰性方式执行类装入，所以类装入过程的某些部分可能在第一次使用类的时候才执行，而不是在装入时执行。

When there is a hierarchy of class loaders, the root class loader, which is the bootstrap class loader, attempts to load the class first.

当类加载器存在一个层次结构时，根类加载器(即引导类加载器)将首先尝试加载类。
