Them d operator, indicated by the percent sign% gives there under ofan integer division. Operations that involve mixed types, such as an int and a double proceed by converting the narrower type (int) to the wider type (double). The result is always the wider type. Literals also have a type. If a number is written as an integer it will be given the type of int, and if a number is written with a decimal point it will be given the type of double double. For example, division of an int by another int always 08) If b is of type int, and e is of type double, what are the types of the following espressions? Write the types of the expressions on your answer sheet. b%3 b. b+4 C.b2.0 e. b+e

Explanation / Answer

Q1. Camel Case - Java uses CamelCase for the purpose of naming variables, classes, methods etc. Its been formed by using the capital letter as the firstletter in each word, so that it can able to read it very comfortably. Example: ComputerHope which is refered as Camel Caps.

Q2. Variable name

Class name

Q3. Curly braces style indentation

Q4. importance of proper indentation in java

Q5. constant value in java

int number_of_days = 365;

this statement can be used for specifying a constant value of the variable throught the program.

Q6. unnamed constant in java

text and numeric. Because, like variables they do not have any specific names. They are just remain constant and it does not change.

Q7.

a) int a - correct

b) int A = wrong format

c) public class FunClass - correct format

d) public static final int my_const = 3; - correct format

e) public int myFunction(int) - wrong format

f) public boolean MyBooleanFunction(boolean b) - wrong format

Q8.

a) b % 3 - int, because b is of type int

b) b + 4 - int, because b is of type int

c) b * 2.0 - double, because b is double

d) c / 2 - double, because c is double

e) b + c - double, because double holds the larger data type

Q11)

static variable

non-static variable

Q12)

import java.util.*;

import java.lang.*;

import java.io.*;

public class Car

{
