How to create an new array from dynamically discovered type

Question

    public static Object toAdjustedArray(Object source, Object addition,
                                         int colindex, int adjust) {
        int newsize = 0;
        Class componentType = null;
        if (source.getClass().isArray()) {
            Object[] arrayIn= (Object[])source;
            componentType = arrayIn[0].getClass();
            newsize = arrayIn.length + adjust;
        else {
            System.out.println("error in ArrayUtil");
        Object[] newarray = new Object[newsize];
        copyAdjustArray(source, newarray, addition, colindex, adjust);
        return newarray;
    }This methods take an array as an input an append new value(s) to it.
I can get the component type of the array (i.e. the class of the array's member). But how can I create a new array of this component type (i.e doing something like componentType[] newarray = new componentType[newsize])?

Answer 1

I fanally found a walkaround trick for my problem.
Their is no way to create an array of a certain type (dynamically dsicovered) in CLDC. But what you can do is to use the instanceof method to determine the type of your array and in a big if statement create the right array.
Here is the final code:
    public static Object toAdjustedArray(Object source, Object addition,
                                         int colindex, int adjust) {
        int newsize = 0;
        if (source.getClass().isArray()){
            Object[] arrayIn= (Object[])source;
            newsize = arrayIn.length + adjust;
        Object arrayElement = null;
        if (addition.getClass().isArray()){
            Object[] temp = (Object[])addition;
            arrayElement = temp[0];
        else{
            arrayElement = addition;
        Object newarray = null;
        if (arrayElement == null){
            newarray = new Object[newsize];
        if (arrayElement instanceof org.hsqldb.Index){
            newarray = new org.hsqldb.Index[newsize];
        else {
            newarray = new Object[newsize];
        copyAdjustArray(source, newarray, addition, colindex, adjust);
        return newarray;
    }
