What I'm trying to accomplish is a switch case that in Java would result in a "cascade" behavior:

switch(var) {
    case 'test':
        Log.d("inside test");
        // break;
    case 'test2':
        Log.d("we are going to print this as well since there is no break statement in the above case");
        Log.d("not going to print this"); 

How can I accomplish the same in Apex? What i tried is:

String test = 'first';

switch on test{
    when 'first' {
        System.debug('inside first');
    when 'lol' {
        System.debug('this will not be printed despite the absence of a break statement in the above case');

Any idea of how to get around this?

Thanks in advance.

  • Multiple switch statements, one for each group of cases is the answer in Apex. Switch fall- through is an anti-pattern for most use cases, thus leaving this answer as a comment/non-answer.

I don't think that Apex is suited to do what you're trying to do (and the Apex switch definitely cannot do this).

The closest I think you'd be able to get is to use a series of independent if statements. Something like...

Boolean cascade = false;
String month = 'September';

if(cascade || month == 'January'){
    // setting cascade to true is like omitting the break in java
    cascade = true;

if(cascade || month == 'February'){
    // setting cascade to false is like including the break in java
    cascade = false;

// The main difference is that a "break" here doesn't stop the other
//   "when" expressions from being evaluated.
// At least by putting the cascade check first, we can short-circuit and avoid
//   _some_ evaluation
if(cascade || month == 'March'){
    cascade = true;

if(cascade || month == 'April'){
    cascade = true;

if(cascade || month == 'May'){
    cascade = true;

// ...and so on

It's a verbose mess, which is a sign that you should probably look for another approach to do whatever it is you're trying to do.
