Somebody please guide me.

Hi Travis Risner-Good Morning,

Thanks for your program.

I have two questions:

On which OS did you run your program: windows or Unix/Linux?

What is the value for i in Print_Numbers(...) ?

Please show me your whole code so that I can understand it.

I am trying to display cpu utilization. I am getting zero value for it.

I am trying to run my sorting program with 1 million integers but my system hangs up.

I am using following following command:

In the above code, I am trying to run my selection sort program with 1000000 integers

Thanks a lot.

I executed the following program:

Following is the  output but cpu usage is zero:

memory usage= 12099584
sdiskusage(total=982900588544, used=141398872064, free=791501631488, percent=15.2)
virtual mem=  11815522304
rss= 12099584

Can you please tell me why cpu usage is zero? How can i get some value for cpu usage?

Also for page faults, the following link says that:


OS(X) and windows, for linix its shared? What does it mean?

I am trying to display system information using psutil.

My code is listed below:

I have provided the comments from where I retrieved the information.

Hi my friend,

What's the value of the netbeans_javahome property in the netbeans.conf file in your NetBeans etc folder?

Yes I tried everything. But sorry this did not work. Always I was getting the same screen which I posted earlier.  You know know this problem was also on StackExchange and there solution was also not direct. They were doing lots of things. My friend used a tool to remove Netbeans from registry and it was pretty simple.

Thanks for your concern.

Thanks for providing me this explanation.
By now I have corrected my code but your comments are good.

I have not tried to execute your code but I have one question for line#25 of your code:

I actually realized my mistake. Argument of "range" starts from 0 and goes up to "n-1", so there is no need of explicitly doing (self.n-1), so I changed it to (self.n).

You might have better reasons for doing this.

Your help is appreciable.

God bless you.

I installed JDK latest version on C drive but still I can't remove NetBeans. I declared all the variables. However, this problem is now solved by removing NetBeans entries from the registry. Of course I called somebody to help me.

I am trying to write a program for selection sort. I got an example program:


I have written the following code:

import random

class SSSort:
  arr = [] # class var access by className.arr
  def __init__(self, n):
     self.n = n

  def generate1000_5digit_RandomNum(self):
     for i in range(self.n):
        num = random.randint(10000, 99999)

     for j in range(self.n):
        print("random {0}".format(SSSort.arr[j]))

  def find_the_min_element(self, i):
     min = i
     for j in range(i+1, self.n-1):
        if (SSSort.arr[j] < SSSort.arr[min]):
           min = j
     return SSSort.arr[min]

  def selectionSort(self):
     for i in range(self.n-1):
        min = self.find_the_min_element(i)
        #swap min and ith element of array
        temp = min
        min = SSSort.arr[i]
        SSSort.arr[i] = temp
     for i in enumerate(SSSort.arr):

  def main(self):

if __name__ == "__main__":
  objSSSort = SSSort(20)

I am getting the following output:

random 98046
random 21192
random 50964
random 81034
random 87750
random 50619
random 32092

(16, 40889)
(17, 40889)
(18, 64008)
(19, 94949)

I think there is problem with swapping.

Somebody please guide me how to correct the above program;

Thanks for your update.

I thought I created an unsized array, but actually its an empty array.

So I can't use indexes with it.
God bless you.

I have created the whole code on my own. I am trying but I can't understand the concept of paramter passing.

I am trying but how much time I can spend on it.

I don't have infinite time.
