Hey everyone! I am a newbie to java and I have what is probably a simple question. I have add a program I am working on to randomly display random numbers from 104, 105, 106, and 108. I have gone about this by creating an array and storing the numbers i want to choose from in the array. Then I try to create a random number generator that references the array. But this is not working.
Hi,
I am having trouble getting back into a loop after an exception has been caught. This is what the program should do...
When I click start button to my quiz game, it goes to this activity. I use this class to random a number and automatically call another activity. I don't know what's wrong but when this class runs, my app is force close. I think it's because of the random .. kindly help me.. Can you suggest another way to random numbers?
How can I use /dev/(u)random on Ubuntu or any *nix sistems ?
I searched at google but I can't find how to :(
I tried this but it says permission denied.
Note : I also tried as root.
/dev/(u)random
sudo /dev/(u)random
sudo -s;/dev/(u)random
Solution :
dd if=/dev/urandom of=~/urandom_test count=4 bs=1024
I'm getting weird syntax's like
print ""
Syntax Error: invalid syntax
also getting
time.sleep(1)
Syntax Error: invalid syntax
elif skill==2:
Syntax Error: invalid syntax
Code:
#Another version of the "adventure game"
#September 14, 2012
import random, os, time, string
os.system("color 1C") # green(2) text on white(F) background
#Warr
I am running the following command on an ubuntu system:
dd if=/dev/random of=rand bs=1K count=2
However, every time I run it, I end up with a file of a different size. Why is this? How can I generate a file of a given size filled with random data?
am using this code to count the remaining tasks in db and it has show that too in list view,here is the code snippet am using,
public void count(){
SQLiteOpenHelper DATABASE_TABLE_REL = null;
SQLiteDatabase mDb = DATABASE_TABLE_REL.getWritableDatabase();
String count = "SELECT count(*) FROM DATABASE_TABLE_REL";
Cursor mcursor = mDb.rawQuery(count, null);
mcursor.moveToFirst();
can you configure it to use /dev/urandom ?/dev/random only returns real random numbers. However, /dev/urandom will first use all the real random numbers then switch to pseudorandom.
Input:
some random text SELECT TABLE1 some more random text
some random text SELECT TABLE2 some more random text
some random text SELECT TABLE3 some more random text
some random text SELECT TABLE1 some more random text
Output:
'SELECT TABLE1' 2
'SELECT TABLE2' 1
'SELECT TABLE3' 1
I am thinking about using
Code:
awk '/SELECT.*/ { [match]++ }'
