Method for adding and drawing several objects

[Pillow]

Hello!

My Issue:

I've made a block class and I want to add and draw several of my blocks to the frame window. As you can see in the code, i've done a temporary "solution", but there should be a better way to add my block objects. I've barely tried to make a arrayList and add each object using loop, something like this:

ArrayList blockList = new ArrayList();

for (int i = 0; i < 13; i++ {
block = new Block(x_pos, y_pos, width, height, color);
blockList.add(i, block);
}

but if I do that, I initiate the object inside the loop making all the block methods unusable.
Is possible to use the objects inside the list as referance like:
blockList.get(5).someBlockMethod();

The issue again if I didn't make myself clear:
Can I add the block objects with a loop or something in that direction and still be able to use it's methods.

(Since I'm pretty new to this, I do not exactly know what I'm doing atm, please bare with me :confused:)
Here's a chunck of my code:

The main method:

public class Pong extends JPanel {

// Oppretter en timer
private javax.swing.Timer timer;

Ball ball;
Player player;
Block block;
Block block1;
Block block2;
Block block3;

// Size of the blocks
private int block_width = 100;
private int block_height = 30;

Color color;

// Initiates the Ball, Player and Blocks
Pong(Color backColor, int width, int height) {

setBackground(backColor);

setPreferredSize(new Dimension(width, height));

// Positions the ball, gives it a color and sets the direction
// and velocity.
ball = new Ball(width / 3, height / 3, 10, Color.black);
ball.setDirection(45);
ball.setVelocity(1);

// Positions the player and sets its velocity.
player = new Player(300, 550, 100, 30, color.black);
player.setVelocity(5);


// !*TEMPORARY*!
// Initiates 13 blocks with diffrent coordinates
block = new Block(0, 0,
block_width, block_height, Color.blue);


block1 = new Block(100 , 0,
block_width, block_height, Color.yellow);


block2 = new Block(200, 0,
block_width, block_height, Color.blue);


block3 = new Block(300 , 0,
block_width, block_height, Color.yellow);

Where the everything is drawn:

public void paintComponent(Graphics g) {
super.paintComponent(g);
ball.drawBall(g);
player.drawPlayer(g);

block.drawBlock(g);

block1.drawBlock(g);

block2.drawBlock(g);

block3.drawBlock(g);

the block class:

class Block {

private int x_pos, y_pos, height, width;

private Color color;

Block(int x, int y, int w, int h, Color c) {

x_pos = x;
y_pos= y;
width = w;
height = h;
color = c;

}

// Draws the blocks
void drawBlock(Graphics g) {
g.setColor(color);
g.fillRect(x_pos, y_pos, width, height);
}

I've uploaded my code in .txt files if you need a closer look.

Is possible to use the objects inside the list as referance like:
blockList.get(5).someBlockMethod();

Define the ArrayList using generics so its get method is defined to return a Block object.
ArrayList<Block>

Works like a charm, thank you!
