Examples of java.lang.Runtime.exec()

java.lang.Runtime.exec()

Executes the specified command and arguments in a separate process.

This is a convenience method. An invocation of the form exec(cmdarray) behaves in exactly the same way as the invocation {@link #exec(String[],String[],File) exec}(cmdarray, null, null). @param cmdarray array containing the command to call andits arguments. @return A new {@link Process} object for managing the subprocess @throws SecurityException If a security manager exists and its {@link SecurityManager#checkExec checkExec}method doesn't allow creation of the subprocess @throws IOException If an I/O error occurs @throws NullPointerException If cmdarray is null, or one of the elements of cmdarray is null @throws IndexOutOfBoundsException If cmdarray is an empty array (has length 0) @see ProcessBuilder
