Description host 2014-03-31 08:04:53 UTC 
For

    String value;
    if (value.equals("0")) {
      // Test 0
    } else if (value.equals("1")) {
      // Test 1
    }

the "Convert to switch" hint is offered.

But for 

    int value;
    if (value == 0) {
      // Test 0
    } else if (value == 1) {
      // Test 1
    }

*no* hint is offered.

The same applies if you use any other primitive datatype where also no hint is offered.

:) the Convert to Switch was done specifically to promote new JDK7 feature, but a generic hint/suggestion can be made with some threshold on number of if-elseif branches. More branches would trigger the hint.
