Answer:
Following are the class "SalespersonSort" code to this question:
public class SalespersonSort //defining a class SalespersonSort
{
public static void main(String[] ax) //defining a main method
{
int id;//defining integer variable
double sales; //defining double variable
String select;//defining String variable
Salesperson[] x = new Salesperson[7]; //crating array as the Salesperson class
Scanner x1= new Scanner(System.in);//creating scanner class object
for(int i=0; i<x.length; i++)//defining loop for input values
{
System.out.print("Enter ID number "+(i+1)+": ");//print message
id = x1.nextInt();//input value
System.out.print("Enter Annual Sales "+(i+1)+": ");//print message
sales = x1.nextDouble(); //input value
x[i]=new Salesperson(id,sales);//hold value in array x
}
System.out.println("Do you want to sort by ID or sales? (Enter ID or sales):");//print message
select= x1.next();//input value
if(select.equalsIgnoreCase("ID"))//define if block that sort value by id
{
for(int i=0; i<x.length; i++)//define for loop to collect value
{
int m= i;//use integerv variable to hold i value
for(int j=i; j<x.length; j++)//define for loop to sort value
{
if(x[j].getID() < x[m].getID())//use if block for check value
m = j;//use integerv variable to hold j value
}
//perform swapping
Salesperson t = x[i];//define calss type variable t to hold aaray value
x[i] = x[m];//inter change value
x[m] = t;//store value in x
}
System.out.println("Sales sorted by ID are ");//print message
for(int i=0; i<x.length; i++)//define for loop to print sort value
System.out.println(x[i]);//print value
}
else//defining else block
{
for(int i=0; i<x.length; i++)//define for loop to collect value
{
int m= i;//use integerv variable to hold i value
for(int j=i; j<x.length; j++)//define for loop to sort value
{
if(x[j].getAnnualSales() < x[m].getAnnualSales())//sort value by sales
m = j;//hold j value in m
}
//perform swapping
Salesperson t = x[i];//define calss type variable t to hold aaray value
x[i] = x[m];//inter change value
x[m] = t;//store value in x
}
System.out.println(" sort value by Annual Sales: "); //print message
for(int i=0; i<x.length; i++)//defining for loop to print value
System.out.println(x[i]);//print value
}
}
}

Explanation:
In the above-given code, a class "SalespersonSort" is defined, inside the class main method is defined, in the method three variables "sales, select, and id" is defined, that is datatype different.
In the class, Salesperson as an array is defined and a scanner class object created that inputs array values and in the string value and a conditional statement is used.
In the if block, it sort values according to id value, and in the else block it sort value according to sales value.
please find the attachment of full code.
