Answer:
Kindly check the explanation section.
Explanation:
Below are the expression given in the question and the corresponding output and Datatype.
(1). Expression = 7/2 + 9.2/2.
Output = 7.6, Datatype = double
(2). Expression = 3.4 + 2 5 f.
Output = 5.9, Datatype = double.
(3). Expression = "whale" . Substring (2,5).
Output = "ale" , Datatype = string.
(4). Expression= (int) 9.2 + 6.0 f.
Output = 15.0 f, Datatype = float.
(5). Expression = (2 <= 1) && (5! = 2) || (8 + 5!= 13).
Output = false, Datatype = boolean
(6) Expression =1.5 f == 1.5?.
Output: “false” , Datatype : “true ”
Output = “false”,
Datatype= String.
(7). Expression = “joey”.charAtt(4).
Output = error, Datatype = error“.
(8). Expression = madmax”.
indexOf(“a”) + 7.
Output: 8 , Datatype = int.
(9). Expression = 2 + 3 + “catdog” + 1 + 2.
Output = “5catdog12”, Datatype = String.
(10). Expression = String.format(“%3.3f”,7.89672).
output = “7.897”, datatype = String.
(11). Expression = “captain”.indexOf(“a”, 2).
Output = 4, datatype = int.
(12). true ? ++3: 3++.
Output = error, dataty = error.
(13). Expression = new String[]{“tony”,“josh”}[0].
Output = “tony”, Datatype = String.
(14). Expression = “patrick”.substring(2) +“lucky”.substring(4).
Output = “tricky”, Datatype = String.
(15). Expression = “popFizz”.indexOf(“o”) + 2.4+ 6L.
Output9.4, Datatype = double.
(16). Expression = “pizza”.indexOf(“z”).
Output = 2, Datatype = int.
