Adding a health bar to a character

I need a health bar to decrement according to the character's remaining HP. However I wouldn't know how to do that because the way my game loads the images

ImageIcon ii = new ImageIcon("Textures/Health/Health100.png");
healthBar = ii.getImage();

I need it to change to replace 100 in "Health100.png" with the characters current health. But I don't think I could replace the 100 with a variable so I wouldn't know how to do that.

Thanks in advance for any help.

You can preload the images which will be better than reloading images as health fluctuates.

When you load your game

 for (int i = 0; i < 100; ++i)
   healthImg[i] = new ImageIcon("Textures/Health/Health" + health + ".png");

Then in your game loop

 healthBar = healthImg[health];

But as the other Jeff suggested, it may be better for you to just not use images (unless your health bar is very fancy)

Instead of having an Image for each health increment and instead of loading all those images into memory (either one at a time or as a lookup list) you can just create a BufferedImage instance of the right dimensions (width/height) and draw directly onto its Graphics object using the Java2D APIs. You could refresh the image as the character's health changes without needing to rely on physical image files.

Can you not simply concatenate the health into the string? e.g.

int health = 100; // change this variable as appropriate
ImageIcon ii = new ImageIcon("Textures/Health/Health" + health + ".png");
