A class **Sorter** contains an array of n integers. Some of the member functions of the Sorter class are given below:

**Class name:** Sorter

**Data members:**

n: to store the number of integers

a[]: an array of n integers

**Member functions:**

Sorter(): constructor

void input(): to input n integers.

void display(): to display the list of integers.

int minimum(int, int): returns the index of the smallest integer in the array between the start index and the last index in the unsorted array.

void sort(): sorts the array in ascending order using exchange selection sort technique and display the sorted array using the display() function.

Specify the class **Sorter**, giving details of the constructor, input(), display(), minimum(), sort(). You do not need to write the main() function.

**Program:**

```
import java.io.*;
class Sorter{
private int n;
private int a[];
public Sorter(){
n = 0;
}
public void input()throws IOException{
InputStreamReader in = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(in);
System.out.print("N = ");
n = Integer.parseInt(br.readLine());
a = new int[n];
}
public void display(){
for(int i = 0; i < n; i++)
System.out.print(a[i] + "\t");
System.out.println();
}
public int minimum(int start, int end){
int small = a[start];
for(int i = start + 1; i <= end; i++){
if(small > a[i])
small = a[i];
}
return small;
}
public void sort(){
for(int i = 0; i < n; i++){
int small = a[i];
int pos = i;
for(int j = i + 1; j < n; j++){
if(small > a[j]){
small = a[j];
pos = j;
}
}
int temp = a[i];
a[i] = a[pos];
a[pos] = temp;
}
}
}
```
