Through the third week of study, I learned about the object and class in the Java language this piece of knowledge point.Java is an object-oriented programming language, object-oriented programs are composed of objects, classes (Class) is a template or blueprint for constructing objects, so learning objects and classes is very important.With regard to the use of objects and classes, if you want to use an object, you must first construct the object, sp

Java Fifth Week learning experience through this week's study, the inheritance has a certain understanding, but not very familiar with the teacher in class according to the previous method of the fifth section of the understanding of the deeper into a bit, but also need a lot of code to grasp the deeper, because the method of sudden change, or there is a little unaccustomed, so now still in the adaptation, Feel that some knowledge is not very deep,

java Tenth Week learning experience Through the tenth week of learning, we learned about generic programming (Generic programming), which is also known as a parameterized type, that is, when defining classes, interfaces, and methods, the type parameter indicates the type of object that will be processed (such as the ArrayList Class). Generic programming means that writing code can be reused by many different types of objects, generics are abstract s
