Combine Two Arrays in Third Array Program - ICSE 2010 Computer Science

Write a program to store six elements in an array P, and four elements in an array Q and produce a third array R, containing all elements of arrays P and Q. Display the resultant array.
Example:
P[] = {4, 6, 1, 2, 3, 10}
Q[] = {19, 23, 7, 8}
R[] = {4, 6, 1, 2, 3, 10, 19, 23, 7, 8}

Java 

import java.util.Scanner;
class MyArray{
    public static void main(String args[]){
        Scanner in = new Scanner(System.in);
        int p[] = new int[6];
        int q[] = new int[4];
        int r[] = new int[10];
        System.out.println("Enter 6 elements:");
        for(int i = 0; i < 6; i++)
            p[i] = Integer.parseInt(in.nextLine());
        System.out.println("Enter 4 elements:");
        for(int i = 0; i < 4; i++)
            q[i] = Integer.parseInt(in.nextLine());
        int i = 0;
        int k = 0;
        for(i = 0; i < 6; i++)
            r[k++] = p[i];
        for(i = 0; i < 4; i++)
            r[k++] = q[i];
        System.out.println("Elements in the third array:");
        for(i = 0; i < 10; i++)
            System.out.println(r[i]);
    }
}

Output

 
 OUTPUT : 
Enter 6 elements:
4
6
1
2
3
10
Enter 4 elements:
19
23
7
8
Elements in the third array:
4
6
1
2
3
