Object-oriented languages ​​have become the modern standard in structured programming. Two modern languages ​​that both implement the object-oriented paradigm are C++ and Java. C++ is a free-form, compiled, intermediate-level language. It was created in 1983 and its most recent revision is C++11, revised in 2011. Java is a class-based and object-oriented language, considered a higher-level programming language than C++. Java is actually based on C and C++. Both languages ​​are widely used on many platforms. As object-oriented programming languages, Java and C++ have characteristics in common. However, the implementation of many features differs between the two. Both languages ​​use a class-based, object-oriented programming style. They also feature generic programming, which is a paradigm that allows you to write code that performs relevant operations on a variety of applicable types. The syntax between Java and C++ is extremely similar. Control flow statements are interchangeable between Java and C++ and include if, if-else, else, switch and while, do-while, and for loops. Statements like “break;” and "continue"; they are used in cycles in both languages. C++ supports one control flow statement that Java does not support, namely the "goto" statement. C++ and Java also share a very similar set of arithmetic operators. Java and C++ are very different in implementation details due to different design philosophies and needs. For one thing, C++ runs directly on a platform's CPU by being compiled directly into machine code, just like C. Java runs in a virtual machine, which is compiled into C and C++. As a result of running on a virtual machine, Java can only access the capabilities of the native platform through the use of the native Java interface,...... middle of paper...... to create a foundation for the creation of SU programs. The C++ programming community writes third-party libraries that can be used by other C++ programmers. Java's standard library includes everything you want or need to create most programs, and it includes the GUI. Both languages ​​are robust and have many useful features. Java features an easy-to-use language based on logical, name-based ideas, with restrictions that prevent unwary or novice programmers from creating silly bugs with their programs. C++ places more responsibility on the programmer, but gives them more freedom in the ways they can implement their solutions. As an amateur programmer, I prefer Java's security features and its extensive standard library, although I want the freedom that C++ provides, even if I learn more about how to handle the responsibility that C++ places on the programmer.
