Now let’s discuss the allowed types ofswitchargument andcasevalues, the requirements for them and how theswitchstatement works with Strings. 4.1. Data Types We can’t compare all the types of objects and primitives in theswitchstatement.Aswitchworks only with four primitives and their wrappers a...

Java Switch Statement with Enum Nested switch Statements The switch statement is Java’s multiway branch statement. It provides an easy way to dispatch execution to different parts of your code based on the value of an expression. As such, it often provides a better alternative than a large s...
One of the changes to the Java syntax with the release of JDK 7 is the ability to use Strings in switch statements. Being able to compare String values in a switch statement can be very handy: JDK 7发行版对Java语法的更改之一是能够在switch语句中使用Strings 。 能够在switch语句中比较String值...
This is not possible with Strings and thus is a drawback of the proposal; however, Case 2 can always be used in place of Case 1. This drawback is not important enough to make the String switch statement undesirable.Case 2: The hash-lookup switch statement...
The switch statement evaluates an expression. The value of the expression is then compared with the values of each case in the structure. If there is a match, the associated block of code is executed. The switch statement is often used together with a break or a default keyword (or both)...
2. Java’s switch Statement Java’s switch statement, while a longstanding feature of the language, has its limitations compared to Kotlin’s when expression. Before Java 7, the switch statement only supported primitives and enumerated types. As of Java 7, it also supports Strings. Let’s exp...

switch语句和if-else语句不同,switch语句可以有多个可能的执行路径。在第四版java编程思想介绍switch语句的语法格式时写到: switch(integral-selector) {caseintegral-value1: statement;break;caseintegral-value12: statement;break;default: statement; }
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...
