Copy to clipboard helper in Java

VendorController.java

// Convert Address object to StringBuilder
StringBuilder sb = new StringBuilder();
	sb.append(vendorService.getVendorBillingAddress(vendor).getLine1()).append("\r\n");
	sb.append(vendorService.getVendorBillingAddress(vendor).getLine2()).append("\r\n");
	sb.append(vendorService.getVendorBillingAddress(vendor).getCity()).append("\r\n");
	sb.append(vendorService.getVendorBillingAddress(vendor).getPostalCode()).append("\r\n");
	sb.append(vendorService.getVendorBillingAddress(vendor).getCountry()).append("\r\n");

// Cast StringBuilder to string, trim it down and remove any empty lines
StringSelection stringSelection = new StringSelection(sb.toString().trim().replaceAll("(?m)^\r?\n", ""));

Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(stringSelection, null);
