Šis ģenerēs 10 8 simbolus garas paroles (a-Z 0-9)

! Saglabā kā GenerateOne.java !

Kompilēt

1. cd uz mapi, kur tu saglabāji .java failu

2. javac GenerateOne.java

Palaist :

1. cd uz mapi, kur stāv .class fails (ja nepārvietoji, tā pati mape, kur .java)

2. java GenerateOne

Ar UNIX bāzētām sistēmām visam tā jābūt. Ar windows var nebūt uzstādīts CLASSPATH un pārējie, tapēc varētu būt jānorāda pilna kompailera atrašanās vieta.

Ja tev nav JDK, pa PM vari paprasīt man jau kompilētu failu.
