crop: has parameters 2 points in cloud. 1 of these 2 points bottom corner, , other diagonally across top corner of rectangle. crop remove points outside rectangle cloud crop image. crop method must deal 2 input points on horizontal or vertical line segment, in case points not on line segment removed, , must deal 2 equal points p1 , p2, in case points p1 removed cloud. for example, if 2 input points (0.0,0,0) , (1.0,1.0), points outside square delimited (0.0,0.0), (0.0,1.0), (1.0,1.0), , (0.0,1.0) removed, if 2 input points (0.0,0,0) , (0.0,1.0), points outside line segment delimited (0.0,0.0), , (0.0,1.0) removed. i'm having hard time approaching logically. if me out thankful. public void crop(point p1, point p2) { point left = points.get(0); point right = points.get(1); point top = points.get(2); point bottom = points.get(3); // point []rectangle2d = {p1,p2}; rectangle2d rect = new rectangle2d.double(p1.getx(), p1.gety(), p2.getx(), p2...

is there way find values of last 5 columns of table? suppose if have table of 20 columns, want select values last 5 columns. any appreciated. in advance. don't. it's stupid. there shouldn't be order columns - should have names. it's convenience when testing or sitting @ db console select * gives them all. there very few cases select * makes sense in live system. can't think of want whatever columns happen "last" on table. if committed doing you'll have query information-schema or system catalogues . list of columns on particular table , build sql query them. however, if aren't in control of table it's meaningless task since won't know information means. if in control of table know column-names there , that's better way it.

ive got question stumped on. reads follows: write import stored procedure take information table (source) , write table (target). im guessing following: create procedure add_data(@name, @surname) begin select name, surname cardholder insert new_table values (name, surname) is logic correct or missing it? you there. since directly copying 1 table another, can use insert ... select ... idiom, so: create procedure add_data @name varchar(100) @surname varchar(100) begin insert new_table(name,surname) select name, surname cardholder end note 2 changes made: how declare parameters sp the values clause should consist of actual values being inserted. since inserting data retrieved table rather fixed values, use select query instead.

this question has answer here: scope of local variable in enhanced for-loop 5 answers if write this: int array[] = {2, 2, 4, 6, 8, 5}; (int : array) { } ..it's ok, if write this: int array[] = {2, 2, 4, 6, 8, 5}; int = 0; (i : array) { } it gives me issues. teacher says wants initialize @ top, how doesn't put int inside of for ... is there other ways write it? the syntax you're using special case of loop, called "for-in" loop. teacher wants more traditional c style loop this: for (int = 0; < array.length; i++) { // need array[i] access elements here } the difference for-in loop doesn't use counter (loop induction variable), uses uninitialised value i , binds name each element of array iterate.
