In above example, the control will jump to respective statement depending on the value of the variable k. If the value of k is ‘a’, then Apple will be printed on the screen. break after System.out.println takes the control out of the switch statement. If break is not included, contr...
Java 12 Enhancements: As of Java 12, you can use switch expressions to return values directly from cases, simplifying the syntax and enhancing code readability. enumDay{MONDAY,TUESDAY,WEDNESDAY,THURSDAY,FRIDAY,SATURDAY,SUNDAY}publicclassSwitchEnumExample{publicstaticvoidmain(String[]args){Day day=Day...

下面我们来看看java switch语句落空通过所有条件,即 case 子句中的所有条件都未能匹配。也就是如果不在 switch case 下使用break语句,则它在第一个匹配之后也会执行接下来的所有 case 中的语句。 示例: public class SwitchExample2 { public static void main(String[] args) { ...
// A simple example of the switch. class SampleSwitch { public static void main(String args[]) { for(int i=0; i<6; i++) switch(i) { case 0: System.out.println("i is zero."); break; case 1: System.out.println("i is one."); ...
import java.util.Scanner; public class GetSwitch { public static void main(String args[]){ Scanner scan=new Scanner(System.in); System.out.println("请输入一个折扣数字"); float rebate=scan.nextFloat()...switch语句的练习 题目: 代码如下: 本体主要用到switch语句和平方根函数,不要忘记使用平方根...
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 ...
To learn more, visit Java break Statement. 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 =...
代码语言:java AI代码解释 intday=2;switch(day){case1:System.out.println("星期一");break;case2:System.out.println("星期二");break;// 其他case语句default:System.out.println("未知");} 在上面的示例中,我们定义了一个整数day,并使用switch语句根据day的值执行不同的代码块。如果day的值为1...
