Below we’ll give some code examples to demonstrate the use of theswitchstatement, the role of thebreakstatement, the requirements for theswitchargument/casevalues and the comparison ofStrings in aswitchstatement. Let’s move on to the example. 2. Example of Use Let’s say we have the foll...

答:在Java 5以前,switch(expr)中,expr只能是byte、short、char、int;从Java 5开始,Java中引入了枚举类型,expr也可以是enum类型;从Java 7开始,expr还可以是字符串(String),但是长整型(long)在目前所有的版本中都是不可以的。 12、用最有效率的方法计算2乘以8? 答: 2 << 3(左移3位相当于乘以2的3次方,右...

In the case of nested loops in Java, the continue statement skips the current iteration of the innermost loop. Working of Java continue statement with Nested Loops Example 3: continue with Nested Loop class Main { public static void main(String[] args) { int i = 1, j = 1; // outer...
Jordan and Syria switch from +02/+03 with DST to year-round +03. Mexico will no longer observe DST except near the US border. Chihuahua moves to year-round -06 on 2022-10-30. Fiji no longer observes DST. Move links to 'backward'. In vanguard form, GMT is now a Zone and Etc/GMT...
