Inheritance:Reuse code, avoid duplication, rewrite methods, new methods, and improve efficiency!3. Object classIs the ancestor of all classes, and any class inherits directly or indirectly from the object!.If a class does not show extends any class, the default inherits the object Class!4. Example: function: Aniaml class, Dog class, Cat class/**animal class*/Public classAnimalextendsobject{//ColorString color; //Age intAge ; Public voideat () {System.out.println ("Food for the Animals"); }

(local variables) Instance variable class, static variable first, Local Variables (local variables) Local variables are declared in a method, constructor, or block Local variables are created when a method, constructor, or block is entered, and once you exit the variable it will be Destroyed. An accessible descriptor cannot be used on a local variable Local variables are visible only in declared methods, constructors, or blocks Local variables are implement

disturb people to rest. It is absolutely forbidden." Many other words are hard to hear. Although I do not have the right to accuse these people, I have the freedom to comment. I want to use the Internet to let these people know my thoughts. Some people always blame everything in the world, but do these people think that their behavior may not be like a dog in many places? Are there any bad places for dogs, is it true that all dogs have advantages? I don't think anyone can say that, For exam

;attack ($z 1); // Suppose the object of a puppy is attacked $z1?>Functions with the same name can be used in different classes, such as the puppy's class zergling, which can also have a function attackNote that starting with PHP5, you can change the properties of an object no matter where it is changed. For example, the above a puppy object is passed as a parameter to the attack function of the machine gun

For example, Mr. Wang has a nickname called puppy. His mother calls the puppy to go home for dinner, that is, he calls Mr. Wang to go home for dinner. Next we will use two lines of code to declare a reference (let's take Xia

parent type, such as animal bird = new bird (); But the class line for the subclass at runtime Any subclass can be replaced by a parent class. Package com. day08.doutai. demo1; public abstract class Animal {private String name; private String gender;/*** meal Method */public abstract void eat (); public String getName () {return name ;} public void setName (String name) {this. name = name;} public String getGender () {return gender;} public void setGender (String gender) {this. gender = gender

domain, those who do not seek the world, and those who do not seek the moment. In the template mode, a piece of code is a subclass of the parent class instantiation and the result is a subclass. People Xiaohong = new Xiaohong (); People xiaofang = new xiaofang (); However, if there are more people, it is impossible for us to declare so many categories, which reflects the grasp of the concept of hierarchy. The view of Tranquility is of great help to our study and life. Therefore, we need to g

tasks within the time limit. You love to gossip and make excuses as efficient as you used to be. In short, you have created your own poor performance evaluation. So what happened? Well, it's simple-you forgot the basics. if you're re looking for a way to get back into gear, revisit the advice you got when you were first starting out in the professional world, and follow these easy (but often ignored) bits of advice. What's wrong with you? Very simple-you forgot the most basic things. If you are
