Explanation:
demo.java Shapes 2 Shapes Polymorphism Create a set of classes derived from an abstract class Shape, which provides a common interface, for managing various 2D geometric shapes. In our model, each Java object will represent a shape somewhere in a Cartesian coordinate system. However, note that unlike in Mathematics, the positive y-axis grows down from the origin. Shapes All shapes have the following properties: color, area, perimeter, location, and bounds. Shapes are mutable, for example any shape can be moved.

Explanation:
Renewable energy is fuel that comes from a source that can be replenished in a short amount of time. This includes solar, wind, water, geothermal power and bioenergy. While renewable energy sources may not always be available – for example, if there is no wind to drive wind turbines, or cloudy days that reduce solar energy – they play an important part in reducing the use of non-renewable resources. Furthermore, many of these resources do not emit greenhouse gases directly into the atmosphere.
 
        
             
        
        
        
A host-based intrusion detection system works similarly to a network-based intrusion detection system in that it can monitor and analyze both the internal workings of a computer system and the network packets on its network ports. 
<h3>What is Host-Based IPS?</h3>
- A host-based intrusion detection system works similarly to a network-based intrusion detection system in that it can monitor and analyze both the internal workings of a computer system and the network packets on its network ports. 
- The Host-based Intrusion Prevention System (HIPS) guards against malicious software and other activities that aim to harm your computer. HIPS uses sophisticated behavioral analysis in conjunction with network filtering's detection capabilities to keep track of active programs, files, and registry keys.
- The integrated endpoint security system known as endpoint detection and response (EDR), also referred to as endpoint threat detection and response (ETDR), combines real-time continuous monitoring and gathering of endpoint data with rules-based automated reaction and analysis capabilities.
