Question

Implement following three methods that passes sturctural tests:

getXStep and getYStep: helper methods, they indicate how far (-1, 0, or 1) have to be taken to take x and y coordinates.
moveAndSet: it moves the piece and changes the value of the new position.

Use the above helper methods in the code of the method.
If the move would make the figure leave the board, cancel the move: the figure remains where it was, the state of the board doesn’t change at all, and the method immediately returns 0.
Otherwise, the method returns the old value of the new position, and its value is set to the second argument. Különben a metódus térjen vissza az új mező régi értékével, és a mező értéke álljon át a paraméterben megadottra.
setAndMove: it is similar to moveAndSet but it changes the value of the position before changing position

@Test

@DisabledIf(notApplicable)

publicvoidmethodGetX() {

it.hasMethod("getXStep", withParams("direction: walking.game.util.Direction"))

.thatIs(FULLY_IMPLEMENTED, USABLE_WITHOUT_INSTANCE, VISIBLE_TO_ALL)

.thatReturns("int");

}

@Test

@DisabledIf(notApplicable)

publicvoidmethodGetY() {

it.hasMethod("getYStep", withParams("direction: walking.game.util.Direction"))

.thatIs(FULLY_IMPLEMENTED, USABLE_WITHOUT_INSTANCE, VISIBLE_TO_ALL)

.thatReturns("int");

}

@Test

@DisabledIf(notApplicable)

publicvoidmethodMoveAndSet() {

it.hasMethod("moveAndSet", withParams("TODOname: walking.game.util.Direction", "TODOname: int"))

.thatIs(FULLY_IMPLEMENTED, INSTANCE_LEVEL, VISIBLE_TO_ALL)

.thatReturns("int");

The class is:

public class WalkingBoard {

privateint[][] tiles; //getter method bhgu

privateintx;

privateinty;

publicstaticfinalintBASE_TILE_SCORE=3;
