Combine text with a name.
Java: Construct a greeting from a fixed prefix and a stored name.
public class Main {
public static void main(String[] args) {
String name = "Ada";
System.out.println("Welcome, " + name);
}
}Expected output EXAMPLE
Welcome, Ada

Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
