This is in java.

Here is the method header given: private String[] expandList(String[] inputList){

The question is to create a new array that is double the size of the array passed in, copies the old data to the new array.

Here is what I've done:

public class oldList{

int initialLength;

String[] oldList;

int items;

public oldList(int initialLen){ initialLength = initialLen; oldList = new String[initialLen]; int Items = 0; }

private String[] expandList(String[] inputList){

oldList = inputList[initialLength*2];

}

}

When I compile, there's the error oldList.java:133: error: incompatible types: String cannot be converted to String[]

I'm confused about the which is string which is array. So I can't even write code to copy the old data to the new array.

Please provide explanations with solutions.

Thank you.
