IGNOU BCA Assignments

Question 1: (a) Write a Java program that enters a 10 digits string as a typical STD telephone number extract the first 3 digits as area code, the 3 digit exchange and the remaining 4 digit numbers as separate strings and print them.

Ans:

Class xyz
{
public static void main (strings args[ ])
{
Int n;
Int Si = new Int [10]
BufferRead br = new Buffer reader new Input stream Reader (System in);
System out print/n (“Enter the phone no”)
S1 = br readline ();
}
}

(b). Implement the Fibonacci series in Java. Your program should invoke both the iterative and the recursive implementation.

Ans:

class factorial
{
int fact (intn)
{
int result;
If (n ==1);
Return;
Else
Result = fact (n-1) * n;
return result;
}
}
class number
{
public static void main
(string args [ ] )
{
intn;
factorial f = new factorial ();
n = f fact (J);
system out print/n (“factorial of 7 is” + n);
}
}

(c). Write a program to find out the minimum and maximum elements of an array.

Ans:

class xyz
{
public static void main (string args[ ])
{
int n,
string s1 = new string [50]
Buffer Read br = new
Input stream reader
(system/n)
System out print/n (“Enter first string”)
S1 = br readline ( );
System out print/n (“Enter second string”)
S2 = br readline ();
n = S1 index of (s2)
If (n == -1)
System out print/n (“String not found”);
Else
System out print/n (“String found at “tnt” position);
}
}
