Hi, I found abnormal compile behavior.

for example, 
-------------------------------------------------------------
Random r = new Random();
float before = r.nextFloat();
float after = r.nextFloat();

int i = 10;

int index = (before < after) ? i - 1 : i;
System.out.println(index + " index!");
-------------------------------------------------------------

Then,

-------------------------------------------------------------
    [iajc] error at int index = (before < after) ? i - 1 : i;
    [iajc]             ^^^^^^^
    [iajc] MainActivity.java:48:0::0 The operator << is undefined for the argument type(s) float, float
    [iajc] error at int index = (before < after) ? i - 1 : i;
    [iajc]
    [iajc] MainActivity.java:48:0::0 Synax error on token "<", << expected
-------------------------------------------------------------

But, when I remove the both parenthesis from "(before < after) ? i - 1 : i" 
to "before < after ? i - 1 : i", I can compile successfully.
