Divide using a fractional number.
Java: Use a floating-point operand to preserve the fractional part of a division.
public class Main {
public static void main(String[] args) {
System.out.println(5.0 / 2);
}
}Expected output EXAMPLE
2.5
Details
Save as Main.java, compile with javac Main.java, and run java Main. Uses the Java 21 standard library.
Tested on Ubuntu 24.04.5 LTS · · openjdk 21.0.12.1 2026-08-18 · openjdk-21-jdk-headless 21.0.12.1+1-1~24.04.4
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.
