Problema ///combinatii de criprografie generare de numere :P

Java has a class called java.util.Random which can generate random numbers. If youwant something to happen with probability 1/25, simply generate a random number

between 1 and 25 (or 0 and 24 inclusive) and check whether that number is equal to

1.

if(new java.util.Random().nextInt(25)==0){

//Do something.

}

Problema inlocuire vocale CORECT!!!

publicclass CompletareVocale {publicstaticvoid main(String args[]) {StringBuffer sb = new StringBuffer("Propozitie propusa spre codare.");String newString = sb.toString();

System.out.println("Sirul inaintea procesului de codare este :" + newString);

String Final= newString.replaceAll("a", "apa").replaceAll("e","epe").replaceAll("i", "ipi").replaceAll("o", "opo").replaceAll("u", "upu");

//repleceAll inlocuieste in sirul newString si inlocuieste in Final toatevocalele cu combinatiile corespunzatoare

System.out.println("Sirul in urma codarii este : " + Final);

}

}

Generatorul de numere aleatoare

function randomString(len, charSet) {

charSet = charSet ||

'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';

var randomString = '';

for (var i = 0; i < len; i++) {

var randomPoz = Math.floor(Math.random() * charSet.length);

randomString += charSet.substring(randomPoz,randomPoz+1);

}

return randomString;

}

Generator 2

unction randomstring(L){

var s= '';

var randomchar=function(){

var n= Math.floor(Math.random()*62);

if(n
