Is there anyway to give cmd prompt command in java

I'm trying to run cmd prompt command using java, i have a source path and destination path and i'm flippig the image. Flipped image should get copied to destination. The image is getting copied but not the flipped image. I'll share my code below, kindly let me know if anything else is needed.

@Test
public void executeCommandJpgDifferentPaths() throws IOException{
    Path resourceDirectory = Paths.get("src\\main\\resources\\download.jpg");
    Path destination = Paths.get(demoFolder.getAbsolutePath(),"download_output.jpg");
    String command = "magick convert -flip resourceDirectory destination " ;
    Boolean output = flipImplementation.executeCommand(command);
    Files.copy(resourceDirectory,destination);
    Assert.assertTrue(output);
    try {
        Thread.sleep(123456789L);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

I have tried this using, 'destinationDirectory.resolve'.We need to use as below :

 @Test
public void executeCommandJpgDifferentPaths() throws IOException{
    Path resourceDirectory = Paths.get("src\\main\\resources");
    Path resourcePath = resourceDirectory.resolve("download.jpg");
    Path destinationDirectory = Paths.get(demoFolder.getAbsolutePath());
    Path destinationPath = destinationDirectory.resolve("download_output.jpg");
    String command = "magick convert -flip " + resourcePath + " " + destinationPath ;
    Boolean output = flipImplementation.executeCommand(command);
    Assert.assertTrue(output);
    try {
        Thread.sleep(123456789L);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

You are using a plain string. But you should be using variables inside.

Replace

String command = "magick convert -flip resourceDirectory destination " ;

with

String command = "magick convert -flip " + resourceDirectory.getAbsolutePath() + " " + destination.getAbsolutePath();
