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...
Theswitchstatement is a selection control flow statement. It allows the value of a variable or expression to control the flow of a program execution via a multi-way branch. It creates multiple branches in a simpler way than using the combination ofifandelse ifstatements. Each branch is ended ...
Java Flow Control Java Basics,Java Control Flow When a Java program is executed, it is executed statement by statement. Generally, all statements are executed sequentially from top to bottom. Sometimes, to apply business logic, we may need to execute statements conditionally, based on the result...

3.8. Control Flow Java, like any programming language, supports bothconditional statementsandloopsto determine control flow. We will start with the conditional statements, then move on to loops, to end with the somewhat cumbersomeswitch statementthat you can use to test for many values of a singl...
We can execute multiple-line control flow statements using JShell the same as Java. The control flow statements like If-else statement, for-loop and while-loop can also be executed in JShell. It recognizes multiple-line statements are prompts with the symbol “…>” to indicate to enter the...
and so on. 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 programmi...
Control Statements Control statements generally direct the flow of programs based on any desired condition. Control mechanisms such asif, else, switch, and loops like for, while, and do-whileare available in Java. These features will enable the implementer to perform the execution of blocks dependi...
