To manipulate vowels in a string
Question 72 : Write a program in Java to accept a word and do the following :
1) If the word starts with a vowel, then move the vowel to the end of the word and add "ay" to it.
Example : owl -> wloay.
2) If there are no vowels in the word, then just add "ay" to it.
Example : sky -> skyay.
3) If the vowel lies in between, then remove all the letters from the beginning till the vowel and add them at the end of the word. Finally, attach "ay" to it.
Example : stop -> opstay.
Java Program :
import java.io.*;
class vowel_changer
{
static String s,s1;
static void main()throws IOException
{
input();
manipulate();
display();
}
static void input()throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter a word : ");
s=br.readLine();
}
static void manipulate()
{
int i,c=0;
char k;
for(i=0;i<s.length();i++)
{
k=s.charAt(i);
if(k=='a' || k=='A' || k=='e' || k=='E' || k=='i' || k=='I' || k=='o' || k=='O' || k=='u' || k=='U')
{
if(i==0)
s1=s.substring(1,s.length())+k+"ay";
else
s1=s.substring(i,s.length())+s.substring(0,i)+"ay";
c=1;
break;
}
}
if(c==0)
s1=s+"ay";
}
static void display()
{
System.out.print("\nManipulated String : "+s1);
}
}
1) If the word starts with a vowel, then move the vowel to the end of the word and add "ay" to it.

Utilities 26 : The nice old cups game
Recently, I had made a nice cups game. Most of you would be familiar with the old cups game, where a ball is kept inside one of the three cups, and while the cups are interchanged amongst themselves, you have to look out for the position of the ball inside that particular cup.
I had posted that game within a package, if you don't remember it, click here. I am posting the game individually now. Enjoy.

Libraries 3 : Mod function
Here's the replica of the widely used Mod Function (%). You may even use it in your program as :
// Rest part of the program is omitted
int m=39,n=7,result;
result=mod.cal(m,n);
System.out.print(result);
Java Program :
class mod
{
static int cal(int number,int mod)
{
for(;;)
{
if(number>=mod)
number=number-mod;
else
return number;
}
}
}
// Rest part of the program is omitted
int m=39,n=7,result;
result=mod.cal(m,n);
System.out.print(result);
Java Program :
class mod
{
static int cal(int number,int mod)
{
for(;;)
{
if(number>=mod)
number=number-mod;
else
return number;
}
}
}

To check whether two numbers are amicable
Question 70 : Write a program in Java to check whether two numbers are amicable or not.
Amicable Number : If two numbers are such that the sum of the perfect divisors of one number is equal to the other number and the sum of the perfect divisors of the other number is equal to the first number, then the numbers are called Amicable Numbers.
Example : 220 and 284.
Java Program :
class amicable
{
static int a,b;
static void input(int m,int n)
{
a=m;
b=n;
display();
}
static boolean check()
{
int s=0,i;
for(i=1;i<a;i++)
{
if(a%i==0)
{
s=s+i;
}
}
if(s==b)
{
s=0;
for(i=1;i<b;i++)
{
if(b%i==0)
{
s=s+i;
}
}
if(s==a)
return true;
else
return false;
}
return false;
}
static void display()
{
if(check())
System.out.print("The numbers are amicable");
else
System.out.print("The numbers are not amicable");
}
}
