Program in Java to accept any number of elements in an array and sort them is descending order using selection sort.
import java.util.Scanner;
class SelectionSortNumber
{
public static void main(String args[])
{
Scanner sc = new Scanner(System.in);
System.out.println("Enter the number of elements: ");
int n = sc.nextInt();
int A[] = new int[n]; //array initialized
System.out.println("Enter the values into the array:");
for(int i=0;i<n;i++)
{
A[i]=sc.nextInt(); //accepting the values into the array
}
//selection sort
for(int i=0;i<n-1;i++)
{
int m=A[i];
int pos=i;
for(int j=i+1;j<n;j++)
{
if(m<A[j])
{
m=A[j]; //find the greatest number index position
pos=j;
}
}
int t = A[pos];
A[pos]=A[i]; //store the smallest value in the location
A[i]=t; // interchange the location
}
//display the sorted array
System.out.println("Elements in descending order are: ");
for(int i=0;i<n;i++)
{
System.out.println(A[i]);
}
}
}
