Answer:
Explanation:
First we must import the package import java.util.*;
we create our scanner and we declare our variables and array
We create a for cycle, and inside the for the If sentence to evaluate every number then we print our negative and positive numbers.
numbers[10]
nega
posi
Scanner num = new Scanner(System.in);
int numbers[] = new int[10];
int nega = 0;
int posi = 0;
for(int i=0; i<=9; i++)
{
System.out.print("Enter the number "+ (i+1) +":");
numbers[i] = num.nextInt();
if(numbers[i]<0){
nega++;
}
else
{
posi++;
}
System.out.println("Negative numbers are: " + nega);
System.out.println("Positive numbers are: " + posi);
}
Explanation:
1. We cast our phones to our televisions so we can see our phone screen on the t.v. This is helpful to society as it exterminiates the need for extra, unnecessary wires connecting to the t.v.
2. We use technology to secure our homes. Many people have even exchanged a door key for a pad lock. This is helpful in the essence that we no longer need to worry about losing our keys, but it is harmful in that pad locks can be easily broken into as opposed to a house key which takes more time. For instance, there is an app where it shows you heat signatures in different colors depending on time. You can easily access a pad locked door by using this app.
3. We pay expenses through our phones (such as eChecks or Applepay) which is helpful in that it makes life easier and quicker, but harmful in that it allows easy access for hackers as well as identity theft. After all, it's not difficult for a hacker or even just an enemy of yours to decrypt a simple password or pin on your phone, especially when people leave their phones exposed in their back jean pockets and are constantly losing their phones in general.
