IfStatement+evaluateCondition()SwitchStatement+evaluateCase() 这里是个简单的部署流程图,用来表示测试的执行顺序: 选择if选择switch启动测试条件选择执行if条件执行switch条件记录性能数据 接下来是安装过程。结合序列图,可以展示测试工具执行不同条件的过程。 MonitorJDKTesterMonitorJDKTester测试using if记录性能测试using ...
需要进行条件语句而必须使用 需要判断的条件很少时,一般不超过5个 使用switch-case: 能用则用 参考资料 Advantage of switch over if-else statementIf…else…if vs switch…case, difference and usage?switch vs if else
Simply put, thebreakstatement is used to exit aswitchstatement. 3. ThebreakStatement Although most of theswitchstatements in real life imply that only one of thecaseblocks should be executed, thebreakstatement is necessary to exit aswitchafter the block completes. If we forget to write abreak,...
A switch statement is evaluated as follows: The switch-expression is evaluated. If switch-expression's value matches a case label, the execution runs from the matched case label until the end of the switch statement. If switch-expression's value does not match a case label, the execution run...
Stringclass(added in Java 7) HerelabelOne,labelTwoandlabelThreeare “compile-time constant expressions” orconstants(the value of the labels must be known at compile-time). We can achieve similar functionality with a chain ofif-else blocks, but theswitchstatement is more readable and clean. ...
intnum=2;if(num==1){System.out.println('One');}elseif(num==2){System.out.println('Two');}else{System.out.println('Not one or two');}#Output:#'Two' Java Copy This code does the same thing as our previous switch statement example, but it uses if-else statements instead. If-els...
对于这种情况,肯定要用if-else语句。顺便说一下,你的switch语句是错误的。 - Anonymous 0 如果你真的想使用 switch 语句,你可以将 mark 除以 10 并让 case 10 和 case 9 等于 A,然后你可以在 case 8 到 case 5 中放置 if 条件语句,default 情况下为 f。 - kimo 0 不幸的是,Java没有像Javascript...
break; case 8: if (((xOne == 0 && yOne == 8) || (xTwo == 0 && yTwo == 8))) System.out.println(i + " *"); break; case 9: if (((xOne == 0 && yOne == 9) || (xTwo == 0 && yTwo == 9))) System.out.println(i + " *"); ...
The switch statement allows us to execute a block of code among many alternatives. In this tutorial, you will learn about the switch...case statement in Java with the help of examples.
