In Java, I want to convert a double to an integer, I know if you do this: doublex=1.5;inty=(int)x; you get y=1. If you do this: inty=(int)Math.round(x); You'll likely get 2. However, I am wondering: since double representations of integers sometimes look like 1.9999999998 or...
I'm trying to sort some arrays in Java using this line: a = sortFacade.sort(2,false, a); where 'a' is an already initialised int array. When I try to compile it, I'm told that the 2 is a long, not an int. I've tried casting it with (int)2 with no luck. I also tried...

int myInt = (int) myDouble; assertNotEquals(myDouble, myInt); After the conversion in the above example,myIntvariable is1, and we can’t restore the previous value1.1from it. Reference variables are different; the reference variable only refers to an object but doesn’t contain the object ...
out.println("Integer value: " + intValue); } } Powered By In this example, the double value doubleValue is explicitly cast to an int type. The conversion results in truncation of the decimal part. Casting Between Object References In Java, you can also cast between object references. ...
