value and type of result variable
Hi Soujanya, the vlaue comes to 17int only and not 17byte because * is having higher precedence then + and after adding the value is no more byte but its changed to int after calculations.

Precedence Operator
Java follows well defined rules for specifying the order in which the operators functions or it is evaluated in an expression. For example, multiplication and division have a higher precedence than addition and subtraction.
When two operators share an operand the operator with the higher precedence gets the preference. For example, 2 + 3 * 3 is treated as 2 + (3 * 5) since multiplication has a higher precedence than addition.
So according to this it turns out to be 15 as it is not having any decimal value then it is denoted by an integer which contains positive whole numbers.

operator
As first preferance goes to higher precedance operators(like first division then multiplication on the basis of their first occurance),3*5 get calculated first =15 after that 2 is added =17 so result is 17
& in java default datatype of Integer type values is "int"
