For loop in java not working [duplicate]

Question

import java.util.Random;
public class RandomHomework
{
    public static void main(String[] args)
    {
        int i;
        Random generator = new Random();
        double randomDecimals = generator.nextDouble()-.04;
        int randomNumber = generator.nextInt(9)+10;
        for(i = 0; i > 100; i++)
        {
            if(randomNumber >= 10.00)
            {
                System.out.println(randomNumber + randomDecimals);
            }
        }
    }
}

I am having a problem with the setup of my for loop and cannot figure it out... It runs perfectly fine when I remove the for loop.

As you can see I tried declaring the i previously but it made no difference.

Please post your code as an MCVE and not as an external link. — Kevin Workman

After you fix your for loop, your program still won't work since it will either skip over printing the randomNumber 100 times, or print the same randomNumber 100 times. You presumably wanted to generate a new random number inside the loop body? — David Conrad

for(i = 0; i > 100; i++)

This says: start with i set to zero and continue as long as it is greater than 100.

This stops right away

The problem is the condition of the loop

for(i = 0; i > 100; i++)

The condition should be i < 100

Your loop condition is always false. You start from i = 0 and say run while i > 100. However, 0 is never > 100 so your loop never happens.

Change

for(i = 0; i > 100; i++)

To

for(i = 0; i < 100; i++)

You must change:

for(i = 0; i > 100; i++)

to:

for(i = 0; i < 100; i++)

for the loop to execute.

You should use

for(i = 0; i < 100; i++)

instead of

for(i = 0; i > 100; i++)

else it would end as soon as it starts since you are checking i > 100

You need to use for(i =0; i<100; i++) cuz your version is ended right away
