Course Introduction:Go language abstract methods include interfaces, function types and type combinations. Several methods are introduced in detail: 1. Interface implements abstract methods. Interface is a way of gathering method declarations together. A set of related methods can be defined through interfaces; 2. Function type implements abstract method. Function type is a special type that can pass and assign functions as values. 3. Type combination implements abstract method. Type combination is a way to combine multiple types into a new type. By nesting new types with fields or methods of other types, the effect of abstract methods can be achieved.

When declaring abstract methods and abstract classes, you need to use the abstract keyword to modify them.
