Unreachable Statement with Break

由 瘦欲@ 提交于 2019-12-20 03:42:30
问题 So I had a previous question but realized I posted the wrong offending code. I've marked the offending statements below. What I am trying to do is set the precedence for each of the operators with that switch statement. Maybe someone could point me in the right direction. Just as a note, I AM running JAVA 7 so String Switch will work. Code opType.java import java.io.*; public final class opType { public static opType ADD = new opType( "Add" ); public static opType SUB = new opType( "Sub" );

1:switch语句 (1)格式： switch(表达式) { case 值1: 语句体1; break; case 值2: 语句体2; break;//如果这里没有break，会case穿透 … default: 语句体n+1; break; } 表达式: 可以是byte,short,int,char JDK5以后可以是枚举 JDK7以后可以是字符串 执行流程: A:首先计算表达式的值 B:和每一个case进行匹配，如果有就执行对应的语句体，看到break就结束。 C:如果没有匹配，就执行default的语句体n+1。 注意事项: A:case后面只能是常量，不能是变量，而且，多个case后面的值不能出现相同的 B:default 可以省略，但是不建议，因为它的作用是对不正确的情况给出提示。 特殊情况： case就可以把值固定。 A,B,C,D C:break 可以省略，但是结果可能不是我们想要的。 会出现一个现象：case穿透。 D:default 可以在任意位置。但是建议在最后。 E:switch语句的结束条件 a:遇到break就结束了 b:执行到末尾就结束了 public static void main(String[] args) { int a = 1; switch (a) { default: System.out.println("default");

问题 How to have the break statement in PostgreSQL? I have the structure like this: for() { for() { if(somecondition) break; } } As per my understanding it should only break the inner for loop? 回答1: There is no BREAK in PL/pgSQL. EXIT terminates the loop. CONTINUE continues at the next iteration of the loop. You can attach a <<label>> to loops and add it as parameter to each of these commands. Then you terminate / continue the labeled loop. Else, it concerns the inner loop. RETURN exits from the

Jumping from one case to the default case in switch statement

问题 switch(ch){ case 'a': //do something, condition does not match so go to default case //don't break in here, and don't allow fall through to other cases. case 'b': //.. case 'c': //.. case '_': //... default: // break; } In a switch statement like above one I enter case 'a', I break only if the condition inside it occurs, otherwise I want to jump to default case. Is there any other way of doing this rather than labels or gotos? 回答1: goto For The Win switch (ch) { case 'a': if (1) goto

Is this a valid (ab)use of lambda expressions?

问题 Like we all know, it's not that easy to break from a nested loop out of an outer loop without either: a goto (Example code.) another condition check in the outer loop (Example code.) putting both loops in an extra function and returning instead of break ing (Example code.) Though, you gotta admit, all of those are kinda clumsy. Especially the function version lacks because of the missing context where the loops are called, as you'd need to pass everything you need in the loops as parameters.

Nested ForEach() in PowerShell

问题 I'm having some troubles with nested ForEach loops in Powershell. First, I need to iterate through list 1. For every object in list 1, I need to iterate through list 2. When I found the resembling object in list 2, I want to go to the next object in list 1. I've tried break, i've tried continue, but it won't work for me. Function checkLists() { ForEach ($objectA in $listA) { ForEach ($objectB in $listB) { if ($objectA -eq $objectB) { // Do something // goto next object in list A and find the
