Course Introduction:Java defines the Long data type Longlg=10L; you only need to add an L after the defined integer type; it is the same as defining the float data type Floatft=5.20F; why do you need to add L and F to the long and float defined by Java? Why do we need to add L when defining long type variables? The basic data type int, occupies 4 bytes, and the value range is -231~231-1. When converted to decimal, it is -2147483648~2147483647. The basic data type long, occupies 8 bytes, and the value range is -263~263- 1. Converted to decimal is -9223372036854775808~92233720368

Course Introduction:1. Explanation (1) To define a generic class, you only need to add type parameters after the class name. Of course, you can also add multiple parameters, such as similar, etc. Therefore, we can use defined type parameters in categories. (2) The most commonly used usage scenario of generic classes is the use of tuples. We know that the return value of the method can only return a single object. If we define a general type and define two or even three type parameters, then build such a tuple data in our general type and transfer multiple objects through generics, so that we can use multiple data at one time. 2. Instance classDataHolder{Titem;publicvoidsetData(Tt){this.item=t;}

Course Introduction:Yes, you can define custom error types in Go by creating a structure that implements the error interface and providing the Error() method to return an error message. Custom error types can be created using the errors.New function or a custom type. In practice, custom error types can provide more specific and meaningful error messages, enhancing the usability and maintainability of the application.

Course Introduction:In the following example, I try to define a PreciseAdder type to simplify the use of instantiated generic types. Unfortunately, the go compiler seems to think that methods defined on generic types are not applicable to PreciseAdder types. I know I can solve this problem through composition, but is there a way to solve this problem through type definition, and if not, what is the reason? packagemaintypeAddableinterface{Add()}typeAdder[TAddable]struct{}func(aAdder[T])DoAdd(){}
