A control structure is a syntactic form in a language to express flow of control. A sequence of statements is executed depending on whether or no the condition it true or false. This means the program chooses between two or more alternative paths. Java
The break statement can be used to terminate a block defined by while, for, or switch statements. Main.java import java.util.Random; void main() { var random = new Random(); while (true) { int num = random.nextInt(30); System.out.print(num + " "); if (num == 22) { break...

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...
The structure of the for loop we saw above is so common that we could generalize it as follows: for (var counter = 0; counter < n; counter++) { statements } In the loop's header, we declare and initialize a variable counter to 0 (remember that you'll need to name this variable ...
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...
Avoid unindented begin-end pairsIn the style shown in Listing 31-24, thebegin-endpair is aligned with the control structure, and the statements thatbeginandendenclose are indented underbegin. Listing 31-24. Java example of unindentedbegin-endpairs ...
However, for the scope of this series, we shall expound on:if-else,for,whileanddo whilestatements. Remember that we already walked throughhow to use next statement in Part 6of this Awk series. 1. The if-else Statement The expected syntax of theif statementis similar to that of the shell...
In this code all the statements surrounded by the braces will be executed whenyourSalesis greater than or equal totarget(see Figure 3.7). Note A block (sometimes called a compound statement) allows you to have more than one (simple) statement in any Java programming structure that otherwise al...
