Open file with default program using java 1.4

问题

The Desktop.getDestop().open(File) launches the associated aplication to open the file.

The Desktop class is available since Java 1.6 - http://docs.oracle.com/javase/6/docs/api/java/awt/Desktop.html

How to do the same using the 1.4 Java version?

回答1:

you can use the following to open files with the default application:

    /* build up command and launch */
    String command = "";
    String file = "FILE IN HERE";
    if (isLinux()) {
        command = "xdg-open " + file;
    } else if (isWindows()) {
        command = "cmd /C start " + file;
    } else
        return;

    try {
        Runtime.getRuntime().exec(command);
    } catch (Exception ex) {
        ex.printStackTrace();
    }

available since 1.0: Runtime.

回答2:

Runtime.exec()
