How to Create Randomly Moving Objects with Individual Timers in Java?

Moving Objects with Random Timers

Your goal is to create moving objects that randomly appear from the screen's bottom, reach a certain height, and then descend. To avoid all shapes starting simultaneously, you need to implement individual timers for each object.

The approach provided below utilizes a Shape class that encapsulates each object's properties, including its random initial delay. Inside the timer's action listener, the Shape methods are called to handle the movement, delay reduction, and drawing.

<code class="java">import java.awt.event.ActionListener;
import java.util.List;
import java.util.Random;

class Shape {

    // Object properties
    int x;
    int y;
    boolean draw;
    int randomDelay; // Delay before the object starts moving

    public Shape(int x, int randomDelay) {
        this.x = x;
        this.y = 0; // Start at the bottom of the screen
        this.draw = false;
        this.randomDelay = randomDelay;
    }

    // Object movement logic
    public void move() {
        if (draw) {
            y++; // Move up or down based on the current state
        }
    }

    // Decrease the delay
    public void decreaseDelay() {
        randomDelay--;
        if (randomDelay <p>This approach ensures that each shape has its own unique random delay, preventing them from starting their movement at the same time.</p>
