Question

A class Mixarray contains an array of integer elements along with its capacity (More than or equal to 3). Using the following description, form a new array of integers which will contain only the first 3 elements of the two different arrays one after another.

Example:

Array1: { 78, 90, 100, 45, 67 }

Array2: {10, 67, 200, 90 }

Resultant Array: { 78, 90, 100, 10, 67, 200}

The details of the members of the class are given below:

Class name	Mixarray
Data members/instance variables:
arr[]	integer array
cap	integer to store the capacity of the array
Member functions/methods:
Mixarray (int mm )	to initialize the capacity of the array cap=mm
void input( )	to accept the elements of the array
Mixarray mix(Mixarray P, Mixarray Q)	returns the resultant array having the first 3 elements of the array of objects P and Q
void display( )	to display the array with an appropriate message.

Specify the class Mixarraygiving details of the constructor(int), void input( ), Mixarray mix(Mixarray,Mixarray) and void display( ). Define a main( ) function to create objects and call all the functions accordingly to enable the task.

Answer 1

import java.util.*;
class Mixarray
{
   int arr[];
   int cap;
   static Scanner sc=new Scanner(System.in);
 Mixarray(int mm)
   {
   cap=mm;
   arr=new int[cap];
   }
 void input()
 {
   System.out.println("Enter the content of the array");
   for (int i=0;i<cap;i++)
     arr[i]=sc.nextInt(); 
 }
 void display()
 { 
   for (int i=0;i<cap;i++)
     System.out.print(arr[i]+" ");
   System.out.println();
 }
 Mixarray mix(Mixarray P,Mixarray Q)
 {
   Mixarray res=new Mixarray(6);
   int k=0;
   for (int i=0;i<3;i++)
     res.arr[k++]=P.arr[i];
   for (int i=0;i<3;i++)
     res.arr[k++]=Q.arr[i];
   return res;
 }
 public static void main()
 { 
   System.out.println("enter the capacity of both the array");
   int c1=sc.nextInt();  int c2=sc.nextInt();
   Mixarray ob1=new Mixarray(c1);
   Mixarray ob2=new Mixarray(c2);
   System.out.println("Enter the content of Ist array");
   ob1.input();
   System.out.println("Enter the content of 2nd array");
   ob2.input();
   Mixarray r=new Mixarray(c1+c2);
   Mixarray res=r.mix(ob1,ob2);
   System.out.println("content of the combined array");
  res.display();
 }
}
