Good program... i will give you 8.5/10 ... there are some scope of improvement...
ReplyDeleteI have added an extra print statement in the loop to print the value of the loop variables viz. number, num1, num2, and num3.
Now, i want you to explain me the every observation you can make.
I believe that programming is not just writing a piece of code, but also understand that what is happening due to the program.
Output:
*****************
C:\Java>java FibonacciNumbers 4
Hello World!
In side only Number method
Enteres Number is valid Number
F Series : 0
>> INFO #4: 0 : 1 : 1
F Series : 1
>> INFO #3: 1 : 1 : 2
F Series : 1
>> INFO #2: 1 : 2 : 3
F Series : 2
>> INFO #1: 2 : 3 : 5
C:\Java>
*****************
Modified Code:
*****************
class FibonacciNumbers
{
public static void main(String[] args)
{
System.out.println("Hello World!");
if(ContainNumber.onlyNumbers(args[0])){
int number = Integer.parseInt(args[0]);
int num1;
int num2= 0;
int num3 = 1;
while(number>0){
System.out.println(" F Series : " + num2);
num1 = num2;
num2= num3;
num3 = num1+num2;
System.out.println(" >> INFO #" + number + ": " + num1 + " : " + num2 + " : " + num3);
number--;
}
}
}
}

//litte change in my programe home u will like it .
ReplyDeleteclass FibonacciNumbers
{
public static void main(String[] args)
{
int number = Integer.parseInt(args[0]); // take the number from argument
String fsereis = "";
if(ContainNumber.onlyNumbers(args[0])){
int num1;
int num2= 0;
int num3 = 1;
while(number>0){
num1 = num2;
num2= num3;
num3 = num1+num2;
fsereis = fsereis + " " + num1;
number--;// decrement the number by one
}
System.out.println(" >> POSTIVE Fibonacci Numbers Sereies for numbber "+ Integer.parseInt(args[0]) + " is :" + fsereis);
}
}
}
Out put is : >> POSTIVE Fibonacci Numbers Sereies for numbber 7 is : 0 1 1 2 3 5 8
this change is good, but the question i asked in the previous comment is still unanswered ...
ReplyDeleteQ: I have added an extra print statement in the loop to print the value of the loop variables viz. number, num1, num2, and num3.

See the modified code and output in the previous comment.
from the F Series : sout looks like we are going to print F Series : for 0,1,2,3
ReplyDeletefrom the INFO #" : sout look like we rae printin Fab sereris for 5 which is 0,1,1 for 4 :1 : 1 : 2,for 3 1 : 1 : 2,for 2: 2 : 3 : 5,for 1: 3 : 5 : 8
