There is a easy solution to remove all uncommitted changes from your working directory in GIT

git fetch origin
git reset --hard origin/master

1 2	git fetch origin git reset --hard origin/master

Note: After executing this command, all uncommitted changes will be removes from your working directory. If you want to save the current work before removing all uncommitted changes, you can do:

git commit -a -m "Backup my work before reset"
git branch backup

1 2	git commit -a -m "Backup my work before reset" git branch backup

Now your work is saved on the branch “backup” in case you decide you want to backup your work to look at it later or diff it.

To remove objects from an array in Java you have to make a List out of the array with Arrays.asList(), and call remove(object) on all the appropriate elements. Then call toArray() on the ‘List’ to make back into an array again. This is not terribly performant, but if you use it in a properly way, you can do it like this.

List<String> list = new ArrayList<String>(Arrays.asList(array));
list.remove(objectToRemove);
array = list.toArray(array);

List<String> list = new ArrayList<String>(Arrays.asList(array));

list.remove(objectToRemove);

array = list.toArray(array);

This does work with not only with String arrays. You can arrays of every Class to remove objects from your array. Here is another simple Example for a List of Cars.

List<Car> list = new ArrayList<Car>(Arrays.asList(array));
list.remove(objectToRemove);
array = list.toArray(array);

List<Car> list = new ArrayList<Car>(Arrays.asList(array));

list.remove(objectToRemove);

array = list.toArray(array);

Thats all. You only have to change the instantiation of the ArrayList to match with your array. So you can delete objects from arrays of any Class.
