As we've seen here,breakandcontinuecan be handy when iterating, though they can often be rewritten withreturnstatements or other logic. 8. Conclusion In this quick article, we learned what control structures are and how to use them to manage flow control in our Java programs. All code presented in this article is availableover on GitHub.
Java, like most other languages, offers conditional flow logic for the program execution. A set of statements may be executed once, more than once, or skipped altogether, and the decision may be made at runtime (that is, at the time of program execution). This makes programming more ...
The while keyword executes the statements inside the block enclosed by the curly brackets. The statements are executed each time the expression is evaluated to true. Main.java void main() { int i = 0; int sum = 0; while (i < 10) { i++; sum += i; } System.out.println(sum); ...
In Java, flow control statements help in the conditional execution of specific statements. All control flow statements are associated with a business condition – when true, the code block executes; when false it is skipped. In Java, a control flow statement can be one of the following: A se...

https://docs.oracle.com/javase/tutorial/java/nutsandbolts/flow.html Language Basics Control Flow Statements 源文件中的语句通常按照出现的顺序从上到下执行。然而,控制流语句通过使用决策制定、循环和分支来分解执行流,使您的程序能够有条件地执行特定的代码块。本节描述Java编程语言支持的决策语句(if-then、if...
JShell is a new interactive command-line tool introduced in Java 9. This tool can also be called REPL (Read-Eval-Print-Loop) because it takes input, evaluates it and returns output to the user via command-line.We can execute multiple-line control flow statements using JShell the same as ...
In the programs we have seen till now, there has always been a series of statements faithfully executed by Python in exact top-down order. What if you wanted to change the flow of how it works? For example, you want the program to take some decisions and do different things depending ...
