Foreword

Like sentient beings, a program must control its world and make choices during its execution.In Java, you use execute control statements to make choices.
Java uses all of C's flow control statements, so if readers have programmed in C or C++ before, they should be very familiar.Most procedural programming languages ​​have some form of control statements, which often overlap across languages.In Java, the keywords involved include if-else, while, do-while, for, return, break and the select statement switch.However, Java does not support the goto statement (this statement has caused many objections, but it is still the most convenient way to solve some special problems).In Java, goto-like jumps are still possible, but with a lot of limitations compared to typical gotos.
