Answer 1

You can execute a program in a couple of ways:

• exec()
• system()
• passthru()
• shell_exec() or the shell execution operator (the backticks, ``)

Which one to use depends on what you want. You should study the above links and figure out which one to use.

Answer 2

Use the exec() function:

exec("java Main.class");
