is something wrong with the code?? it keeps saying invalid .java name

I have tried everything i saw on the forums, not one thing helped me. I really am stumped on how to import a java model... here is my code:

// Made with Blockbench 3.5.0
// Exported for Minecraft version 1.14
// Paste this class into your mod and generate all required imports

public class molabear extends EntityModel {
    private final RendererModel leg;
    private final RendererModel legtwo;
    private final RendererModel legthree;
    private final RendererModel legfour;
    private final RendererModel body;
    private final RendererModel head;

    public molabear() {
        textureWidth = 60;
        textureHeight = 60;

        leg = new RendererModel(this);
        leg.setRotationPoint(-8.0F, 24.0F, -8.0F);
        leg.cubeList.add(new ModelBox(leg, 4, 19, 0.0F, -5.0F, 2.0F, 3, 4, 1, 0.0F, false));
        leg.cubeList.add(new ModelBox(leg, 0, 15, 3.0F, -1.0F, 0.0F, -3, 1, 3, 0.0F, false));

        legtwo = new RendererModel(this);
        legtwo.setRotationPoint(8.0F, 24.0F, -8.0F);
        legtwo.cubeList.add(new ModelBox(legtwo, 17, 0, -3.0F, -5.0F, 2.0F, 3, 4, 1, 0.0F, false));
        legtwo.cubeList.add(new ModelBox(legtwo, 16, 9, -3.0F, -1.0F, 0.0F, 3, 1, 3, 0.0F, false));

        legthree = new RendererModel(this);
        legthree.setRotationPoint(-8.0F, 24.0F, -8.0F);
        legthree.cubeList.add(new ModelBox(legthree, 14, 27, 0.0F, -6.0F, 15.0F, 3, 5, 1, 0.0F, false));
        legthree.cubeList.add(new ModelBox(legthree, 26, 0, 3.0F, -1.0F, 13.0F, -3, 1, 3, 0.0F, false));

        legfour = new RendererModel(this);
        legfour.setRotationPoint(-8.0F, 24.0F, -8.0F);
        legfour.cubeList.add(new ModelBox(legfour, 25, 0, 13.0F, -6.0F, 15.0F, 3, 5, 1, 0.0F, false));
        legfour.cubeList.add(new ModelBox(legfour, 7, 15, 16.0F, -1.0F, 13.0F, -3, 1, 3, 0.0F, false));

        body = new RendererModel(this);
        body.setRotationPoint(-5.0F, 19.0F, -6.0F);
        body.cubeList.add(new ModelBox(body, 0, 42, -3.0F, -4.0F, -1.0F, 16, 4, 14, 0.0F, false));

        head = new RendererModel(this);
        head.setRotationPoint(0.0F, 19.0F, -8.0F);
        head.cubeList.add(new ModelBox(head, 38, 0, -3.0F, -5.0F, -1.0F, 6, 6, 4, 0.0F, false));
        head.cubeList.add(new ModelBox(head, 2, 15, -2.0F, -2.0F, -2.0F, 4, 1, 1, 0.0F, false));
        head.cubeList.add(new ModelBox(head, 43, 20, -4.0F, -3.0F, -2.0F, 1, 1, 1, 0.0F, false));
        head.cubeList.add(new ModelBox(head, 43, 20, 3.0F, -3.0F, -2.0F, 1, 1, 1, 0.0F, false));
    }

    @Override
    public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5) {
        leg.render(f5);
        legtwo.render(f5);
        legthree.render(f5);
        legfour.render(f5);
        body.render(f5);
        head.render(f5);
    }

    public void setRotationAngle(RendererModel modelRenderer, float x, float y, float z) {
        modelRenderer.rotateAngleX = x;
        modelRenderer.rotateAngleY = y;
        modelRenderer.rotateAngleZ = z;
    }
}

thank you
