starting an app with splash screen but when I run it

I get this error**"java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ImageView.setAnimation(android.view.animation.Animation)' on a null object reference"****

public class MainActivity extends AppCompatActivity {
   
 private static int SPLASH_SCREEN = 5000;
    Animation topAnim,bottomAnim;
    ImageView image;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_main);
    topAnim = AnimationUtils.loadAnimation(this, R.anim.top_animation);
    bottomAnim = AnimationUtils.loadAnimation(this, R.anim.bottom_animation);


    ImageView Logo = findViewById(R.id.Logo);
    TextView slogan = findViewById(R.id.slogan);

    image.setAnimation(topAnim);
    slogan.setAnimation(bottomAnim);
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            Intent intent = new Intent(MainActivity.this,Dashboard.class);
            startActivity(intent);
            finish();
        }
    },SPLASH_SCREEN);
}

}
