TITLE OF THE LAB REPORT EXPERIMENT
C - Java Syntax Similarity: Array, Conditionals, Loops
OBJECTIVES/AIM
The objective of this lab is to design and implement a Java program covering the following
topics:
● Analyzing and comparing the similarities in syntax and functionality between the
programming languages C and Java
● Understanding java syntax, array conditions and loops
● Implementing different problems like Fibonacci numbers, and odd-even number checking
solved in Java.
Title: Checking of odd and even number
PROCEDURE / ANALYSIS / DESIGN
The flowchart to check odd and even number is mentioned below:
IMPLEMENTATION
The program imports the Scanner class from the java.util package. A class named OddEven has
been created. The main method takes a number from the user using scanner object. Then it
checks the number even or odd by conditional statements.
TEST RESULT / OUTPUT
All test cases have passed for different input values, including zero, positive and negative
integers, and large numbers. So, the program correctly identifies whether a given number is even
or odd.
Input
Output
-11
-11 is a Odd.
0
0 is Even.
29
29 is a Odd.
-101
-101 is a Odd.
10696
10696 is Even.
Title: Summation of factorial odd number series
PROCEDURE / ANALYSIS / DESIGN
The flowchart of main part to calculate the summation of factorial odd number series is:
IMPLEMENTATION
The program imports the Scanner class from the java.util package. A class named
FactorialOddNumSeries has some variables, a constructor, four methods. In the main method, it
takes input for x and n and checks n to be even. Then, it creates object of this class to run Result0
and display() method.
TEST RESULT / OUTPUT
All test cases have passed for different input values, including zero, positive and negative
integers, and large numbers. So, the program correctly identifies whether a given number is even
or odd.
Input
Output
x=3 n=6
7.199999999999999
x=3 n=11
Value of n must be even... Try again!
x=11 n=26
329292.2725487378
ANALYSIS AND DISCUSSION
The lab achieved its objective by checking a number odd or even and calculating the factorial
summation of odd number series. It took me time to understand the second problem and identify
how to solve it. I changed the logic in Result() method a few times to obtain an accurate
calculation. From this, I learned how to solve a problem step by step. This lab gave me a basic
idea about implementing Java syntax, array and conditional statements, and how to use Apache
NetBeans.
SUMMARY:
The lab report titled "C - Java Syntax Similarity: Array, Conditionals, Loops" explores the
syntactical similarities between C and Java in handling arrays, conditionals, and loops. It shows
that both languages have some similar structures, making it easier for programmers familiar with
one language to learn the other.
