android - What is difference between ZoomTo and ZoomBy in google map -


currently, working google map , may have confusion between 2 methods. don't differentiate working of 2 method so, can explain me difference between zoomby() , zoomto()

code:

mmap.animatecamera(cameraupdatefactory.zoomby(zoomlevel)); mmap.animatecamera(cameraupdatefactory.zoomto(zoomlevel));

cameraupdatefactory.zoomto(float) gives cameraupdate changes zoom level given value, while keeping other properties same.

cameraupdatefactory.zoomby(float) , cameraupdatefactory.zoomby(float, point) give cameraupdate increases (or decreases, if value negative) zoom level given value. latter fixes given point on screen such remains @ same location (latitude/longitude) , may change location of camera in order achieve this.

from official documentation here

so in short zoomto changes zoom level given value, while zoomby increases or decreases ( e.g. zoomto(20) camera have zoom level set 20, if zoom level 20 , call zoomby(-5), zoom level become 15)

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
