Lab 8

Lab Description: In this lab, I had to create a program to analyze data that a user input. First i would ask the user to say what kind of elements they will give and then they will input their elements. The program will organize their elements for them.

CODE:

import java.util.LinkedList;
import java.util.Scanner;
import java.util.Stack;
import java.util.TreeSet;
import java.util.Collections; 

public class lab8 {

private static Scanner input;

public static void main(String[] args) {
	input = new Scanner(System.in);
	System.out.print("Type of Elements of Analyze (1 = String, 2 = Double, 3 = Integer)  ");
	int link = 0;
	link = input.nextInt();
	
	if (link == 1) {
		int a = 0;
		System.out.println("You have selected String. ");
		System.out.print("Enter Amount of Strings: ");
		int b = input.nextInt(); 
		
		Stack stack = new Stack();
		LinkedList list1 = new LinkedList();
		LinkedList list2 = new LinkedList();
		TreeSet treeset = new TreeSet();
		
		while(a < b) {
			System.out.print("Strings: ");
			String c = input.next();
			list1.addFirst(c);
			stack.push(c);
			treeset.add(c);
			a++; 
		}

		list2.addAll(list1);
		Collections.sort(list2);
		
		System.out.println("Strings Entered in Order: " + stack);
		System.out.println("Strings Entered in Reversed Order: " + list1);
		System.out.println("Strings Entered in Ascending Order: " + list2);
	}
	
	if (link == 2) {
		int a = 0;
		System.out.println("You have selected Double. ");
		System.out.print("Enter Amount of Numbers: ");
		int b = input.nextInt(); 
		
		Stack stack = new Stack();
		LinkedList list1 = new LinkedList();
		LinkedList list2 = new LinkedList();
		TreeSet treeset = new TreeSet();
		
		while(a < b) {
			System.out.print("Numbers: ");
			double c = input.nextDouble();
			list1.addFirst(c);
			stack.push(c);
			treeset.add(c);
			a++; 
		}

		list2.addAll(list1);
		Collections.sort(list2);
		
		System.out.println("Numbers Entered in Order: " + stack);
		System.out.println("Numbers Entered in Reversed Order: " + list1);
		System.out.println("Numbers Entered in Ascending Order: " + list2);
	}
	
	if (link == 3) {
		int a = 0;
		System.out.println("You have selected Integer. ");
		System.out.print("Enter the Amount of Numbers: ");
		int b = input.nextInt(); 
		
		Stack stack = new Stack();
		LinkedList list1 = new LinkedList();
		LinkedList list2 = new LinkedList();
		TreeSet treeset = new TreeSet();
				
		while(a < b) {
			System.out.print("Numbers: ");
			Integer c = input.nextInt();
			list1.addFirst(c);
			stack.push(c);
			treeset.add(c);
			a++; 
		}

		list2.addAll(list1);
		Collections.sort(list2);
		
		System.out.println("Numbers Entered in Order: " + stack);
		System.out.println("Numbers Entered in Reversed Order: " + list1);
		System.out.println("Numbers Entered in Ascending Order: " + list2);
	}
}
}
