Swift Study Notes (23)-Swift generic knowledge, swift Study Notes

The concept of generics also exists in Java. Generics can make code more refined and are an optimization for data types. Now there is the same requirement: Write a struct, and then judge whether the integer is equal. The implementation code and output are as follows:

.

If there is another demand, you need to determine whether the two floating point types are equal. What should we do? The code implementation is basically the same as above, but we have to re-write the floating point code:

.

The above two codes will cause code reusability to deteriorate and become redundant. If you use generics for implementation, it will become very simple:

.

Is the implementation of generics very high. Let's upgrade our code to B.
