Java programming languages

I'm looking logic help on if/else statement for chooseDirection(final Map theNeighbors) method. I'm good with the light that biycle can pass through but I need help on direction method. The option that I have was Terrain.WALL for wall, Terrain.STREET for street, Terrain.CROSSWALK for cross walk, Terrain.GRASS for grass, Terrain.TRAIL for trail, Terrain.LIGHT for light.

/** * Grass. */ GRASS('-'),

/** * Street. */ STREET('|'),

/** * Light. */ LIGHT('+'),

/** * Wall. */ WALL('X'),

/** * Trail. */ TRAIL('.'), /** * Crosswalk. */ CROSSWALK('#');
