Template method

        public void execute() {
		this.setNewPosition();
                // some code
		if (!isMovePossible()) {
			// some code
		}
		this.moveCharacter();
		// some code
	}

	public boolean isMovePossible() {
                return !this.outsideFieldBorders()
				&& !this.clashesWithNeighborCharacter()
				&& !this.clashesWithTool();
	}

        public boolean clashesWithTool() {
		// some code
	}

        public boolean clashesWithNeighborCharacter() {
		// some code
	}

        public void moveCharacter() {
		this.field.moveCharacter(this.character, newPosition);
	}

        public abstract boolean outsideFieldBorders();

        public abstract void setNewPosition();

Template method (2)

        @Override
	public boolean outsideFieldBorders() {
		if (this.currentPosition.x == this.field.getElements()[0].length - 1) {
			return true;
		}
		
		return false;
	}
	@Override
	public void setNewPosition() {
		this.newPosition = new Position(currentPosition.x + 1,
				currentPosition.y);
	}

DownCommand.java
