    <p>I am trying to make a loop that gets passwords from an array list, hashes them, and then passes the hashed passwords back into a Person object.</p> <pre><code>import java.util.ArrayList; public class CompanyDatabase { public ArrayList&lt;Person&gt; getPeople() { ArrayList&lt;Person&gt; people = new ArrayList&lt;Person&gt;(); String[] u = {"Joe","Stan","Leo","John","Sara","Lauren"}; String[] p = {"pass4321", "asdfjkl", "genericpw", "13579", "helloworld", "companypass"}; for(int j = 0; j &lt; u.length; j++){ Person temp = new Person(u[j],p[j]); people.add(temp); } return people; } } </code></pre> <hr> <pre><code>import java.util.ArrayList; import java.util.Scanner; public class CompanyDatabaseDriver { private static Scanner scan = new Scanner( System.in ) ); public static void main(String args[]) { CompanyDatabase bcData = new CompanyDatabase(); ArrayList&lt;Person&gt; people = bcData.getPeople(); Hash_SHA hasher = new Hash_SHA(); for(int i=0;i&lt;people.size();i++){ System.out.println(people.get(i).getPassword()); } // i know i have to use a variation of // String hashString = hasher.getHash(passString); // but do not really know what to do with it } </code></pre> <p>} </p> <pre><code>public class Person { private String username; private String password; public Person(String un, String pw){ username = un; password = pw; } public void setUsername(String un){ username = un; } public void setPassword(String pw){ password = pw; } public String getUsername(){ return username; } public String getPassword(){ return password; } </code></pre> <p>}</p> <p>Currently I just have the loop printing out the plain text passwords and then ending the loop. Any help would be amazing. Thank you very much.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
