Insert String at End of ArrayStringLog

[noble]

Trying to figure out how to insert a String at the "End" of an Array String Log. Here is the code I have so far, right now the "insert" and "insertAtEnd" are obviously doing the same thing but I'm not sure how to make it do otherwise:

public void insert(String element)
// Precondition: This StringLog is not full.
//
// Places element into this StringLog.
{
if (isFull())
lastIndex++;
else {
lastIndex++;
log[lastIndex] = element;
}
}
public void insertAtEnd(String element)
{
if (isFull())
lastIndex++;
else{
lastIndex++;
log[lastIndex] = element;
}
}


I'm using a class called UseStringLog to insert strings using this method:

log.insert("String 1");
log.insert("String 2");

etc.

and it prints like this:

1. String 1
2. String 2

etc.

How would I change the "insertAtEnd" to get the string to insert before "String 1"?

Here is the entire ArrayStringLog class if that helps:

public class ArrayStringLog implements StringLogInterface {
protected String name; // name of this StringLog
protected String[] log; // array that holds strings
protected int lastIndex = -1; // index of last string in array

public ArrayStringLog(String name, int maxSize)
// Precondition: maxSize > 0
//
// Instantiates and returns a reference to an empty StringLog object
// with name "name" and room for maxSize strings.
{
log = new String[maxSize];
this.name = name;
}

public ArrayStringLog(String name)
// Instantiates and returns a reference to an empty StringLog object
// with name "name" and room for 100 strings.
{
log = new String[100];
this.name = name;
}

public void insert(String element)
// Precondition: This StringLog is not full.
//
// Places element into this StringLog.
{
if (isFull())
lastIndex++;
//throw new FullLogException("Full Log\n");
else {
lastIndex++;
log[lastIndex] = element;
}
}
public void insertAtEnd(String element)
{
if (isFull())
lastIndex++;
else{
lastIndex++;
log[lastIndex] = element;
}
}

public boolean isFull()
// Returns true if this StringLog is full, otherwise returns false.
{
if (lastIndex == (log.length - 1))
return true;
else
return false;
}

public int size()
// Returns the number of Strings in this StringLog.
{
return (lastIndex + 1);
}

public boolean contains(String element)
// Returns true if element is in this StringLog,
// otherwise returns false.
// Ignores case differences when doing string comparison.
{
boolean moreToSearch;
int location = 0;
boolean found = false;
moreToSearch = (location <= lastIndex);

while (moreToSearch && !found)
{
if (element.equalsIgnoreCase(log[location])) // if they match
found = true;
else
{
location++;
moreToSearch = (location <= lastIndex);
}
}

return found;
}

public void clear()
// Makes this StringLog empty.
{
for (int i = 0; i <= lastIndex; i++)
log[i] = null;
lastIndex = -1;
}

public String getName()
// Returns the name of this StringLog.
{
return name;
}

public String toString()
// Returns a nicely formatted string representing this StringLog.
{
String logString = "Log: " + name + "\n\n";

for (int i = 0; i <= lastIndex; i++)
logString = logString + (i+1) + ". " + log[i] + "\n";

return logString;
}
}
