We can pass a class as a parameter just like any other object. Besides, we can use theClassclass to represent classes in Java and pass instances of this class as arguments to methods. Here’s a simple implementation: publicclassExample{publicstaticvoidprocessClass(Class<?> clazz){ System.out...

For example, the lambda expression directly accesses the parameter x of the method methodInFirstLevel. To access variables in the enclosing class, use the keyword this. In this example, this.x refers to the member variable FirstLevel.x.However, like local and anonymous classes, a lambda ...
