I have a validate method in a bean class that works and now I want to
condense it into a for loop.

Here is what I have:

//firstname and lastname are declared earlier
public boolean validate()
{
    boolean allOk=true;
    if (firstName.equals("")) {
      errors.put("firstName","Please enter your first name");
      allOk=false;
    }
    if (lastName.equals("")) {
      errors.put("lastName","Please enter your last name");
      allOk=false;
    }
    return allOk;
  }

My attempt doesnt work because I cant seem to figure out how to put
the array reference in the key part of the errors.put method:

public boolean validate()
{
    boolean allOk=true;
    String [] myarray = {firstname, lastname}
    for(int i=0;i < myarray.length;i++)
    {
    if (myarray[i].equals("")) {
      errors.put(myarray[i],"Please enter your " + myarray[i]);
      allOk=false;
    }
    }
    return allOk;
  }

The results dont validate any of my data so I assume I have something
wrong with my array. Please advise.

Is this your actual code? Did you even try to compile it?
What does the compiler say about your line
String [] myarray = {firstname, lastname}
???
I can only guess (thanks to your selective code pasting) that
you are atempting
String [] myarray = {firstName, lastName};
or
String [] myarray = {getFirstName(), getLastName()};
