**Tested code with buffered image with different thickness values**:

Graphics2D g = bufferedImage.createGraphics();

int height = //image height

int width = //image height

int borderWidth = //border thickness

int borderControl = 1;

//set border color

g.setColor(Color.BLACK);

//set border thickness

g.setStroke(new BasicStroke(borderWidth));

//to fix issue for even numbers

if(borderWidth%2 == 0){

borderControl = 0;

}

g.drawLine(0, 0, 0, height);

g.drawLine(0, 0, width, 0);

g.drawLine(0, height – borderControl, width, height – borderControl);

g.drawLine(width – borderControl, height – borderControl, width – borderControl, 0);

Here's how to do this : Border with colored line with thickness 5.

Border linebor = BorderFactory.createLineBorder(new Color(0xAD85FF), 5);

If you are drawing on a Graphics2D object, you can use the setStroke() method:

Graphics2D g2;
double thickness = 2;
Stroke oldStroke = g2.getStroke();
g2.setStroke(new BasicStroke(thickness));
g2.drawRect(x, y, width, height);
g2.setStroke(oldStroke);

If this is being done on a Swing component and you are being passed a Graphics object, you can downcast it to a Graphics2D.

Graphics2D g2 = (Graphics2D) g;
