If I may introduce a bug
The JVM will manage it for me
Ensuring both security and portability
Then I'll write my code once, and run it everywhere
With Static and Strong Typing
Will let my programs be type safe
Garbage collection

For int i equals zero
i less than foo, i plus plus
System out dot print L-N
Hello world
(Semicolon) Public void fase method
Int pippo equals zero
While pippo less than foo (Boolean metal)
System out dot print L-N (Equals false)
Hello world (If metal double equals false)
For int i equals zero
i less than foo, i plus plus
System out dot print L-N
Hello world (String Joey DeCaio equals null)
(Semicolon)

While pippo less than foo
System out dot print L-N
