create an example that demonstrates proper utilization of a callback

Provide an example of a case utilizing polymorphism. Explain how your example benefits from polymorphism.

import java.io.*;
import java.util.Scanner;


class userinput {
public static void main(String args[])

throws IOException
{
Scanner s=new Scanner(System.in);
String[]a=new String[4];
System.out.println("Enter 'STOP' to quit.");
for(int i=0;i<4;i++)
{
System.out.println(i+1+".Enter your input:");
String temp=s.nextLine();
a[i]=temp;
}

{

Scanner in = new Scanner(System.in);
String str[] = new String[4];

System.out.println("Enter 'STOP' to quit.");
for(int i=0; i<4; i++) {
str[i] = in.next();
if(str[i].equals("stop")) break;
System.out.println(str[i]);
System.out.println(a[i]);
}
System.out.println("**************");
System.out.println(" RESULT ");
System.out.println("**************");


for(int i=0;i<4;i++)
{
for(int j=0;j<4;j++)
{
String temp=a[i];
String tempB=a[j];
if(temp.compareTo(tempB)<0)
{
a[i]=tempB;
a[j]=temp;
}
}
}

for(int i=0;i<4;i++)
{
System.out.println(a[i]);

Your task is to create a JAVA program that will accept as many inputs as the user desires until the user enters “STOP”.

The program should then alphabetize the inputs and display the result. No external sorting classes are allowed.

Java programming this application need to have these factors and I am confused how to code them Help?


A salesperson will continue to earn a fixed salary of $55,000. The current sales target for every salesperson is $165,000.
The sales incentive will only start when 75% of the sales target is met. The current commission is 14% of total sales.
If a salesperson exceeds the sales target, the commission will increase based on an acceleration factor. The acceleration factor is 1.8.
The application should ask the user to enter annual sales, and it should display the total annual compensation.
Your program should use a class method to compute the calculated compensation. The method should take one parameter for the total sales, and the method should access the salary, sales target, sales incentive and acceleration factor from the class variables. The method should be non static, and be used as part of an object.The application should also display a table of potential total annual compensation that the salesperson could have earned, in $5000 increments above the salesperson’s annual sales, until it reaches 50% above the salesperson’s annual sales. The source code must demonstrate the use of conditional and looping structures.The application should have at least one class, in addition to the application’s controlling class.
