A lot of people will see in the motherboard parameters about the capacitance, which is the main board of solid-state capacitor price is usually higher, the solid-state capacitor and the liquid capacitor what is the difference? Solid capacitors are all known as solid aluminu

Abstract class and interface are two mechanisms supported for the definition of abstract classes in Java. It is precisely because of the existence of these two mechanisms that give Java powerful object-oriented capabilities. Abstract class and interface have great similarity in support for the definition of abstract classes, and can even be replaced with each other, therefore, when defining abstract classes, many developers may choose abstract classes
