Hi, world, i have i little probleme with a class array, i have some strange message like "ClassCastException: Ljava.lang.object; cannot be cast to [Ltest_array$myArray....."

I can use splice with an array object?
I make all my code, it's more easy if you want try.

Thank you very munch for your help!


////////////////MAIN

import processing.opengl.*;
myArray [] ArrayBig = new myArray[3];

void setup(){
 size(800,600,OPENGL);
 background(0);
 mouseX = 40;
 for(int i=0;i<ArrayBig.length;i++){
   ArrayBig[i] = new myArray(Xref+50*i,y);

 }
}

int y = 100;
int x=0;

void draw(){
 background(0);

 for(int i=0;i<ArrayBig.length;i++){
   ArrayBig[i].update(Xref+-2*50+50*i,y);
 }
 change();
}


int Xref = 100;
int multi = 1;

void change(){  
 if(mouseX>Xref){  
   changeRight();
   multi++;
   Xref += 50;
 }
 if(mouseX<Xref-100){  
   changeLeft();
   multi--;
   Xref -= 50;
 }  
}


void changeRight(){
 myArray [] ArrayBig2 = (myArray[]) subset(ArrayBig,1);
 ArrayBig = ArrayBig2;
 myArray [] ArrayBig3 = (myArray[]) append(ArrayBig,new myArray(Xref+-2*50+50*3,y));
 ArrayBig = ArrayBig3;
}

void changeLeft(){
 myArray [] ArrayBig2 = (myArray[]) subset(ArrayBig,3);
 ArrayBig = ArrayBig2;
//My problem is here....
 myArray [] ArrayBig3 = (myArray[]) splice(ArrayBig,(new myArray(Xref+-2*50+50*3,y)),0);
 ArrayBig = ArrayBig3;
}

////////////////CLASS myArray
class myArray{
int R,V,B;
 
 myArray(int x,int y){
   R = round(random(255));
   V = round(random(255));
   B = round(random(255));
   rect(x,y,50,50);
 }

 void update(int x,int y){
   stroke(255);
   strokeWeight(.1);
   fill(R,V,B);
   rect(x,y,50,50);
