Is there an equivalent in Java to typedefs in C/C++?

We can find that Java and C/C++ programming languages have many similarities in syntax and functionality. However, some features are omitted in Java, such as "typedef". Anyone with a C/C++ background must have heard of the "typedef" keyword and often wonder if there is anything equivalent to typedef in Java? Simply put, Java does not provide a direct equivalent to typedef. The creators of Java replaced this functionality with classes. In fact, classes do even more than typedefs do. Replacing C/C++ typedefs in Java? Before exploring the answer to the given question, let us first discuss about typede in C/C++
