All of them apply
Explanation:
Green computing is the process of using environmental friendly computers and its associated components, accessories and other supporting devices.
Virtualization helps us to reduce the number of hardware that we are using.
Grid computers helps us to reduce the use of number of machines and thus supporting the environment in a right way.
Recycling process. Any material that we use needs to be recycled effectively and also in an environmental friendly way.
Autonomic computing uses eco-friendly system which in turn hugely support green computing.
Answer:
Runnable.
Explanation:
Java is an all round programming language which is typically object-oriented and class-based. It was designed by James Gosling, developed by Sun microsystems and released officially on the 23rd of May, 1995. Java programming language is designed to have only a few implementation dependencies as possible because it was intended to be written once, and run on any platform.
Java makes concurrency to be available to software developers through the application programming interface (API) and the language. Also, it supports multiple threads of execution, by making each thread have its respective program counter and method-call stack, which then allow concurrent executions with other threads.
The preferred means of creating multithreaded Java applications is by implementing the runnable interface. An object of a class that implements this interface represents a task to perform. The code is public void run ().
