default Case in Java switch-case The switch statement also includes an optional default case. It is executed when the expression doesn't match any of the cases. For example, class Main { public static void main(String[] args) { int expression = 9; switch(expression) { case 2: System.ou...
While our example is a bit arbitrary, the point is that we’ve got access to more of the Java language here. 5.3. Returning InsideswitchExpressions As a consequence of the distinction betweenswitchstatements andswitchexpressions,it is possible toreturnfrom inside aswitchstatement, but we’re not...
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...
Example Using the switch statement to execute a block of code based on user input, from a prompt box: vartext; varfavDrink = prompt("What's your favorite cocktail drink?"); switch(favDrink) { case"Martini": text ="Excellent choice! Martini is good for your soul."; ...
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...

We can also check for vowel or consonant using a switch statement in Java. Example 2: Check whether an alphabet is vowel or consonant using switch statement public class VowelConsonant { public static void main(String[] args) { char ch = 'z'; switch (ch) { case 'a': case 'e': cas...
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 ...
switch语句是Java的多路分支语句。它提供了一种基于一个表达式的值来使程序执行不同部分的简单方法。因此,它提供了一个比一系列if-else-if语句更好的选择。switch语句的通用形式如下: switch (expression) { case value1: // statement sequence break;
