Merge two arrays and sort the merge array
Q. Write
a program in Java to accept two integer arrays from the user and join them into
a third array.
After
joining the arrays, sort the final array in ascending order using Bubble sort
technique.
Sample
Input: Array A [ ] = {10,2,23,4,15};
Array B
[ ] = {60,7,80,99,10};
Sample
Output: The final Array after
joining
is :
10 2 23
4 15 60 7 80 99 10
The
final Array after sorting is : 2 4 7 10 10 15 23 60 80 99
Solution:
In the
following the program two array arr1[] and arr2[] are merge into a single array
arr3[]. Here first array arra1[] with five values first added to one by one to
the third arr3[] and then arr2[] five values are added to arr3[]. After merging
we sort the array with the Bubble sort array technique. Finally, we print the sorted
array.
public
class MergeArrayAndSort
{
public static void main(String args[])
{
int arr1[]={10,2,23,4,15}; // First Array
int arr2[]={60,7,80,99,10}; // Second
Array
int arr3[]=new int[10]; // Third Array
int i, k=0; // use as a counter for
third array
int j, temp;
System.out.println("First
Array");
for(i=0; i<5; i++)
{
System.out.print(arr1[i] + "
");
}
System.out.println();
System.out.println("Second
Array");
for(i=0; i<5; i++)
{
System.out.print(arr2[i] + "
");
}
System.out.println();
// Merging of two array
// First array into the third array
for(i=0; i<5; i++)
{
arr3[k]=arr1[i];
k++; //k=5
}
// Second array into the third array
for(i=0; i<5; i++)
{
arr3[k]=arr2[i];
k++;
}
System.out.println("After Merging
of Two arrays into third array");
for(i=0; i<k; i++)
{
System.out.print(arr3[i] + "
");
}
System.out.println();
// Sort the Merge Array with Bubble sort
for(i=0; i<k-1; i++)
{
for(j=0; j<k-1 - i; j++)
{
if(arr3[j]>arr3[j+1])
{
temp = arr3[j];
arr3[j] = arr3[j+1];
arr3[j+1] = temp;
}
}
}
// Print the sorted order
for(i=0; i<k; i++)
{
System.out.print(arr3[i] + "
");
}
System.out.println();
}
}
