For example, class Main { public static void main(String[] args) { int expression = 2; // switch statement to check size switch (expression) { case 1: System.out.println("Case 1"); // matching case case 2: System.out.println("Case 2"); case 3: System.out.println("Case 3");...
Switchhas evolved over time. New supported types have been added, particularly in Java 5 and 7. Also, it continues to evolve —switchexpressions will likely be introduced in Java 12. Below we’ll give some code examples to demonstrate the use of theswitchstatement, the role of thebreakstatem...
Java 12 introduced the switch expressions which can compute the value for the whole switch statement and assign its value to a variable. It is very similar to other normal Java statements. 2.1. Return value with Arrow Syntax Let us rewrite the last example, with a switch expression. Noticelin...
Here’s a simple example: intday=3;switch(day){case1:System.out.println('Monday');break;case2:System.out.println('Tuesday');break;// ...}#Output:#'Tuesday' Java Copy In this example, we have a switch statement that checks the value of the variableday. Depending on the value, it ...
传统 switch 语句的基础支持 支持类型: 仅限整型 (byte、short、int) 和字符型 (char)switch(...
Example intday=4;switch(day){case1:System.out.println("Monday");break;case2:System.out.println("Tuesday");break;case3:System.out.println("Wednesday");break;case4:System.out.println("Thursday");break;case5:System.out.println("Friday");break;case6:System.out.println("Saturday");break;case...
Working of break Statement with Nested Loops Here, the break statement terminates the innermost while loop, and control jumps to the outer loop. Labeled break Statement Till now, we have used the unlabeled break statement. It terminates the innermost loop and switch statement. However, there is...
在上面的示例中,我们同样使用switch语句来根据变量number的值执行不同的操作。当number的值为3时,打印出"Number is 3",然后使用return语句立即退出main方法。因此,程序不会执行switch语句之后的代码,也不会输出"Switch statement is finished"。 小结 通过使用break或return语句,我们可以在Java中退出switch循环。break语...
break: Terminates theswitchstatement, preventing fall-through. default: Executes if no case value matches the expression. Examples Example 1: Basic Usage publicclassSwitchExample{publicstaticvoidmain(String[]args){int day=3;switch(day){case1:System.out.println("Monday");break;case2:System.out.pri...
