What are the advantages of using generics in java

This article mainly introduces "java use generics advantages what", in daily operation, I believe many people in java use generics advantages what problems there are doubts, Xiaobian consulted all kinds of information, sorted out simple and easy to use operation methods, hope to answer "java use generics advantages what" doubts help! Next, please follow the small series to learn together!

Stronger type checking at compile time.

The Java compiler checks for strong typing of generic code if the code violates type safety.

It's wrong. Correcting compile-time errors is easier than correcting run-time errors, which may be difficult to find.

3. Eliminate display type conversion.

4. After the coding adopts generic reconstruction, you can see that there is no need for coercion.

This will be extremely convenient for programmers.

Enable programmers to implement generic algorithms. By using generics, programmers can implement generic algorithms that integrate different types, can be customized, and are type-safe and readable.

examples

List list = new ArrayList(); list.add("hello"); String s = list.get(0); // no cast This is the end of the study on "What are the advantages of Java using generics", hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
