Whats wrong with this

class Machine {

You've made infinite loop. for cycle works like this:

// for ( initial set up; condition to check when looping; what to increment )
for ( i = 0 ; i <= 10; i++ )

In your case (char) System.in.read() != 'S' is not related to i variable anyhow, that's why cycle increments i inifinitely

Checkout in the web more on loops:
