Non-static method referenced from a static context

Question

I have two errors both the same and they follow below:

class FBox {//...}
class FBPlayer
{
    //Initialized instances
    FBox game = new FBox();
    **FBPillar pillar = new FBPillar();**
    **FBObjects objects = new FBObjects();**
    //Lots o Properties...

    public boolean get_Alive() { return this.b_PlayerAlive; }
    public void set_Alive(boolean alive) { this.b_PlayerAlive = alive; }

    //My Error ridden Method
    public void checkCollision()
    {
        if(get_YPos() >= **objects**.get_Ground())
                          ^My Error was incorrect name for my instance
        {
            set_Alive(false);
        }
        else if(get_Bounds().intersects(**pillar**.get_Bounds()))   
                                ^My Error was incorrect name for my instance
        {
            set_Alive(false);
        } 
    }

class FBPillar
{
    public int get_Bounds() {return 'the variable'; }
}

class FBObjects
{
    public int get_Ground() {return 'the variable'; }
}

The error is in the if statement as well as the else if statement When i run it it returns the error:

FBox.java:178: error: non-static method get_Bounds() cannot be referenced from a static context
               else if(get_Bounds().intersects(**FBPillar**.get_Bounds()))

The same error for the if statement but with FBObjects.get_Ground()) ^

Answer 1

Whose bounds are you talking about? You probably mean

if (get_Bounds().intersects(pillar.get_Bounds())) {
    …
}

I'd also add that

 FBPlayer player = new FBPlayer();

means that a player contains a player, which is probably isn't what you intended.
