Write down the result of each expression in the output column and specify the datatype of the result.Datatype should follow the Java Standards. If the output is a String, surround it with " ";if the output is char surround it with ‘ ’. Floats should have an ‘f’ or ‘F’ at the end, longs should have an ‘L’ or ‘l’ at the end (generally avoid using lowercase ‘l’ because it can be confusing).

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.
