Program Listing
class Main
{
// Selection Sort to Sort the given array of Strings
static void selectionSort(String arr_items[],int n)
{
for(int i = 0; i < n - 1; i++)
{
int min_index = i;
String minStr = arr_items[i];
for(int j = i + 1; j < n; j++)
{
if(arr_items[j].compareTo(minStr) < 0)
{
minStr = arr_items[j];
min_index = j;
}
}
if(min_index != i)
{
String temp = arr_items[min_index];
arr_items[min_index] = arr_items[i];
arr_items[i] = temp;
}
}
}
public static void main(String args[])
{
String arr[] = {"Zebra","Dog","Cobra","Lion","Bear","Tiger","Rabbit","Cat","Buffalo"};
int n = arr.length;
System.out.println();
System.out.println("\tSorting of Strings Using Selection Sort in Java\n");
System.out.println();
// Printing the array before sorting
for(int i = 0; i < n; i++)
{
System.out.println(i+": "+arr[i]);
}
System.out.println();
selectionSort(arr, n);
System.out.println("After Sorting of Strings\n");
// Printing the array after sorting
for(int i = 0; i < n; i++)
{
System.out.println(i+": "+arr[i]);
}
