For the life of me I cannot understand why this code does not fill the array with random values. I would really appreciate any help.
Code:import java.util.Random;
public class test
{ public static void main (String[] args)
{ int[] num = new int[10];
Random generator = new Random();
for (int i=0;i>10;i++)
{ num[i]=generator.nextInt(50)+1;
System.out.println(num[i]); //this should be outputing the values of num[] but it is not??
}
}
}
Check your for loop conditions, the middle one may be wrong. :o:
Just to spare your life haha the for loop you got the < backwards you are telling it to continue until i is not > 10 but i = 0 is not greater than 10 so it never starts.Quote:

Also, you should fix your code formatting. Don't start code on the same line as an opening bracket, and use a little more whitespace to improve readability. Also, you will want to follow Java naming rules with your class names starting with capital letters and method and variable names with lower-case letters. So for instance, your code may want to look like...
This may seem trivial, and perhaps with your small program it is, but it becomes very important when you are trying to get others to understand larger more complex programs. So it's better to start good habits now.Code:import java.util.Random;
public class Test {
public static void main(String[] args) {
int[] num = new int[10];
Random generator = new Random();
for (int i = 0; i < 10; i++) {
num[i] = generator.nextInt(50) + 1;
System.out.println(num[i]);
}
}
}
