Is it a bad practice to have multiple returns? -


sonar lint rule "methods should not complex" (squid:methodcyclomaticcomplexity) has example of using more 1 return statement in program block. (see https://groups.google.com/forum/#!topic/sonarqube/btvgof6tw7e cyclormatic complexity calculation rules)

the returns shortens codes in branch, , result smaller code blocks. example,

      int findbranchnumber(string input) {         if ("branch1".equals(input)) {             return 1;         }         if ("branch2".equals(input)) {             return 2;         }         // ....         return -1;     }

the alternative use method variable (in case) or bigger blocks. whoever reads code has read whole method before he/she realize first 3 lines relevant "branch1".

please advise ...

i'm show in example. careful if allocate resources (for example file opening, memory allocation , on) , need freed on return function. in case can used trick goto line hire described in first answer https://stackoverflow.com/a/245761
