Is there a good way to spawn multiple instances of a custom class without typing it out?

i.e. CustomClass instace1 = new CustomClass();

This method works but is inefficient when I need to create 100+ instances of the custom class. I was thinking that a for loop would work well for this, but I don't know how to use a for loop to create multiple instances.

Here is my code:

import processing.opengl.*;

int spacer = 8;
int sizer = 40;

ColorSquare square001 = new ColorSquare(0,spacer,random(0,(width-sizer)));
ColorSquare square002 = new ColorSquare(0,spacer,random(0,(width-sizer)));
ColorSquare square003 = new ColorSquare(0,spacer,random(0,(width-sizer)));
//all the way up to
ColorSquare square126 = new ColorSquare(2,(spacer*7+sizer*6),random(0,width-sizer));

void setup(){
 size(700,352, OPENGL);
 smooth();
 noStroke();
 frameRate(40);
 colorMode(RGB, 255, 255, 255, 100);
}

void draw(){
 background(0);
 square001.updater();
 square002.updater();
 square003.updater();
 //all the way up to
 square126.updater();
}

//ColorSquare(color, v row, starting h place)
class ColorSquare {
 int locY, fillColor;
 float locX, xVelo, xAccel, mass, mouseMass, massDist, grav, xGrav;
 ColorSquare(int a,int b, float c) {
   fillColor = a;
   locY = b;
   locX = c;
   xVelo = 0;
   xAccel = 0;
   mass = (random(2,6) * 100);
   mouseMass = (random(5,10) * 1000);
   massDist = 0;
   grav = 0;
   xGrav = 0;
 }
 void updater(){
   massDist = dist(mouseX, mouseY, locX, locY);
   if(massDist<40){massDist = 40;}
   grav = mass * mouseMass / pow(massDist,2)* 5;
   xGrav = grav * ((mouseX - locX)/massDist);
   xAccel = xGrav / mass;
   xVelo = xVelo + xAccel;
   locX = locX + xVelo;
   if(locX>=(width-sizer)){locX = (width-sizer);}
   else if(locX<=0) {locX = 0;}
   switch(fillColor) {
     case 0:
       fill(255,0,0,30);
       break;
     case 1:  
       fill(0,255,0,30);
       break;
     case 2:
       fill(0,0,255,30);
       break;
   }
   rect(locX, locY, sizer, sizer);
 }
}

ColorSquare[] ColorSquareArray = new ColorSquare[126];
for (int i=1; i<127; i++){
  ColorSquareArray[i] = new ColorSquare(0,spacer,random(0,(width-sizer)));
}
