Java array :Java pass by reference and pass by value? -


i trying reverse bitmap array, without modifying source array. problem source array getting reversed. doing wrong or suppose other way? help.

private galleryadapter galleryadapter; private reversegalleryadapter rgalleryadapter;    public void oncreate(bundle savedinstancestate) {     galleryadapter = new galleryadapter(this, imagethumbnails, imagepaths,             videothumbnails, videopaths);      imagegrid.setadapter(galleryadapter);      rgalleryadapter = new reversegalleryadapter(this, reversebarray(videothumbnails), reversesarray(videopaths),             reversebarray(imagethumbnails), reversesarray(imagepaths));      imagegrid2.setadapter(rgalleryadapter); }  private bitmap[] reversebarray(bitmap[] v){     bitmap[] btemp;     btemp = v;     int len = btemp.length;     bitmap temp;     (int = 0; < len/2; i++)     {         temp = btemp[i];         btemp[i] = btemp[len-1 - i];         btemp[len-1 - i] = temp;     }     return btemp; }  private string[] reversesarray(string[] s){     string[] stemp;     stemp =s;     int len = stemp.length;     string temp;     (int = 0; < len/2; i++)     {         temp = stemp[i];         stemp[i] = stemp[len-1 - i];         stemp[len-1 - i] = temp;     }     return stemp; }

with btemp = v; referring same object.

you can use in case clone() method make copy of array:

btemp = v.clone();

then can freely modify , return it.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
