title: Java arrays for list of people, age, and weight
body: <p>I have an assignment that uses arrays but I can not seem to get it to print the correct results. The assignment asks to create a class which has functions that allow the user to :</p>
  
  <p>1- insert a name, age, and weight for an infinite number of people, until the name "FINISHED" has been entered.</p>
  
  <p>2- It should be able to display all the peoples names, ages, and weights, sorted from lightest weight to the heaviest.</p>
  
  <p>3- The user should also be able to display the age and weight of a person that they searched for (if exists).</p>
  
  <p>Here's what I got so far:</p>
  
  <pre><code> public static void main(String[] args) {
      Scanner kb = new Scanner(System.in);
  
  
      ArrayList&lt;Persons&gt; peopleAr = new ArrayList&lt;Persons&gt;();
      Persons ewPeople = new Persons();
      ewPeople.name = "Peter";
      ewPeople.age = 20;
      ewPeople.weight = 70.0;
      peopleAr.add(ewPeople);
  
      for (int i = 0; i &lt; peopleAr.size()+5; i++) {
  
          System.out
                  .println("Enter the number of the action you'd like to preform:");
          System.out.println("1. Add new profile.");
          System.out.println("2. View all prfiles (lightest to heaviest).");
          System.out.println("3. Search for a person.");
          System.out.println("4. Exit.");
  
          int key = kb.nextInt();
  
          switch (key) {
              case 1:
                  System.out
                          .println("Enter the required information. Enter 'finished' in the name field to "
                                  + "return to main menu. ");
  
                  Persons newPeople = new Persons();
  
                  newPeople.name = "abc";
  
                  while (!newPeople.name.equals("finished")) {
  
                      System.out.println("Enter name: ");
                      newPeople.name = kb.next();
  
                      System.out.println("Enter age: ");
                      newPeople.age = kb.nextInt();
  
                      System.out.println("Enter weight: ");
                      newPeople.weight = kb.nextDouble();
  
                      peopleAr.add(newPeople);
                  }
                  break;
  
              case 2:
  
                  for (int j = 0; j &lt; peopleAr.size(); j++) {
                      System.out.println(peopleAr.get(i) + "  "
                              + peopleAr.get(i) + "   " + peopleAr.get(i + 2));
                  }
                  break;
  
              case 3:
                  String nameTemp = "abc";
                  while (!nameTemp.equalsIgnoreCase("done")) {
                      System.out
                              .println("Enter the name you'd like to search. Enter 'done' to return to main menu. ");
                      nameTemp = kb.next();
                      boolean check = peopleAr.contains(nameTemp);
                      if (check = true) {
                          int p = peopleAr.indexOf(nameTemp);
  
                          System.out.println(peopleAr.get(p) + "  "
                                  + peopleAr.get(p + 1) + "   "
                                  + peopleAr.get(p + 2));
  
                      } else {
                          System.out
                                  .println("There is no match for your search.");
  
                      }
                  }
                  break;
              case 4:
                  System.exit(0);
          }
  
      }
  }

  <p>So, The first part works (except for little bugs).
  The second part does not return the values as a string. I've tried using the <code>toString()</code> method and converting the objects to a string with a loop but none of them work. I need some help with displaying the objects as strings instead of "lab04.Persons@14eac69".
  The third part also has some issues, but I believe they are related to the second issue since the compiler probably won't like comparing strings to objects.</p>
  
  <p>I know there a lot of things that look like garbage in my code, but they are there to hold things together or otherwise I'd get errors. I wanna fix the main functions before picking the small bugs and cleaning up the code.</p>
