Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.
Answer:
c. your friend can hash all possible options and discover your secret.
Explanation:
SHA-256 is a set of hash functions that was designed by the NSA. SHA-2 is considered an upgrade on the set that was its predecessor, SHA-1. A hash is a mathematical function that condenses data in a process of one-way encryption. SHA-256 creates hash algoritms that are considered irreversible and unique. However, one of the properties of hashing algorithms is determinism, which means that any computer in the world would be able to compute a particular hash and get the same answer.
Answer:
Explanation:
The following code is written in Java and loops through 10 times. Each time generating 2 random dice rolls. If the sum is 10 it breaks the loop and outputs a "You Win" statement. Otherwise, it outputs "You Lose"
import java.util.Random;
class Brainly {
public static void main(String[] args) {
UseRandom useRandom = new UseRandom();
boolean youWin = false;
for (int x = 0; x<10; x++) {
int num1 = useRandom.getRandom(6);
int num2 = useRandom.getRandom(6);
if ((num1 + num2) == 10) {
System.out.println("Number 1: " + num1);
System.out.println("Number 2: " + num2);
System.out.println("You Win");
youWin = true;
break;
}
}
if (youWin == false) {
System.out.println("You Lose");
}
}
}
class UseRandom{
public int getRandom(int n)
{
Random r=new Random();
int rand=r.nextInt(n);
return rand;
}}
