Out of the two code snippets below, does any of the approach has some benefit over the other?

for(int i:list) {
    if(condition 1) {
      //do something
      continue;
    }
    if(condition 2) {
      //do something
      continue;
    }
    if(condition 3) {
      //do something
      continue;
    }
}

versus

for(int i:list) {
    if(condition 1) {
      //do something
    }
    else if(condition 2) {
      //do something
    }
    else if(condition 3) {
      //do something
    }
}

Do the two approaches differ only in coding style or do we get any performance improvement in one of them.

Prefer whichever is most readable. The JIT can easily transform a->b where b is whichever version is "better". – Elliott Frisch Nov 14 '18 at 04:43

In the second example, it is recognizable that an `if` will not be entered into if a previous `if` has already been entered into. – Scary Wombat Nov 14 '18 at 04:44
in addition to the other comments, `continue;` is taking an extra line per condition :) – Kartik Nov 14 '18 at 04:45
`if-else if` is easier to read and presents the desired logic better - IMHO – MadProgrammer Nov 14 '18 at 04:48
