3. A class Mix has been defined to mix two words, character by character, in the following manner: [ISC 2020]
The first character of the first word is followed by the first character of the second word and so on. If the words are of different
length, the remaining characters of the longer word are put at the end. Example: If the First word is “JUMP” and the second
word is “STROLL”, then the required word will be “JSUTMRPOLL”
Some of the members of the class are given below:
Classname : Mix
Data Member/Instance variable
wrd : to store a word
len : to store the length of the word
Member Functions/Methods
Mix( ) : default constructor to initialize the data members with legal
initial values
void feedword() : to accept the word in UPPER case
void mix_word(Mix P, Mix Q) : mixes the words of objects P and Q as stated above and stores the
resultant word in the current object
void display() : displays the word
Specify the class Mix giving the details of the constructor(), void feedword(), void mix_word(Mix, Mix) and void display().
Define the main() function to create objects and call the functions accordingly to enable the task.
Ans. import java.util.*;
class Mix
{
String wrd;
int len;
static Scanner x=new Scanner(System.in);
Mix()
{
wrd="";
len=0;
}
void feedword()
{
System.out.println( "Enter a word in UPPER CASE");
wrd=x.next();
len=wrd.length();
}
void mix_word(Mix P,Mix Q)
{
int s=(P.len <Q.len)? P.len:Q.len;
for(int i=0;i<s;i++)
wrd += P.wrd.charAt(i)+""+Q.wrd.charAt(i);
if (P.len > Q.len)
wrd +=P.wrd.substring(Q.len);
else
wrd +=Q.wrd.substring(P.len);
}
void display()
{
System.out.println("WORD = " + wrd);
}
public static void main(String[] args)
{
Mix obj=new Mix();
Mix obj1=new Mix();
Mix obj2= new Mix();
obj.feedword();
obj1.feedword();
obj2.mix_word (obj,obj1);
obj2.display();
}
}
