Java : Arrarys

Arrays in Java are also objects.we use the following syntax:
int[ ] arry; // There is no size

We create new size like below
arry = new int[5]



To show array length
arry.length


To see the array value
int[ ] arry = { 1, 2, 3, 4, 5}
or 
arry[1] = 20;

Here is example code :




public class Demo {
           public static void main(String[ ] args) {
                  int[ ] arry ;
                  arry = new int[5];
                  arry[0] = 33;
                  arry[1] = 34;
                  arry[2] = 35;
                  arry[3] = 36;
                  arry[3] = 37;    
  
                  for ( int i = 0; i < arry.length; i++)
                  {
                         System.out.println(arry[i]);
                  }
 
                  
           }
}

mount samba on ubuntu

sudo mount.cifs //hostname/sharename ~/mounts/sharename -o user=username,pass=password

sshfs on ubuntu

Use sshfs instead, there is no setup necessary at all and you get "proper" mount points that are recognized by any application:

sudo apt-get install sshfs

Mount the remote filesystem with

sshfs user@host:/path /local/mount/point

and unmount with

fusermount -u /local/mount/point

更新git

使用的是ubuntu 10.04,出現這個問題
fatal: git 1.7.2 or later required
git版本太舊
處理的方法如下:
$ sudo add-apt-repository ppa:git-core/ppa
$ sudo apt-get update
$ sudo apt-get install git
就可以更新到新版的git
