Java之switch分支结构基本使用 快速入门 案例:Switch01.java 请编写一个程序,该程序可以接收一个字符,比如:a,b,c,d,e,f,g a 表示星期一,b 表示星期二 … 根据用户的输入显示相应的信息.要求使用 switch...(a-g)"); char c1 = myScanner.next().charAt(0);// //在java中,只要是有值返回,就是一...
A unique characteristic of the switch statement in Java is the ‘fall through’ behavior. When a match is found in the case values, and there’s no break statement to terminate the current case, Java will execute all subsequent cases until it encounters a break statement or reaches the end ...

Java的switch 语句 就会接着执行下一个case分支语句。这种情况相当危险,常常会引发错误switch语句的执行过程如下:表达式的值与每个case语句中的常量作比较。如果发现了一个与之相匹配的,则执行该case语句后的代码。如果没有一个case常量与表达式的值相匹配,则执行default语句。当然,default语句是可选的。如果没有相匹配...
Wrapper classes have also been available since Java 5. Of course,switchargument andcasevalues should be of the same type. 4.2.NonullValues We can’t pass thenullvalue as an argument to aswitchstatement. If we do, the program will throwNullPointerException, using our firstswitchexample: ...
When Java reaches abreakkeyword, it breaks out of the switch block. This will stop the execution of more code and case testing inside the block. When a match is found, and the job is done, it's time for a break. There is no need for more testing. ...
