Saya menyahpepijat keseluruhan aplikasi dan menggunakan kaedah pengelogan untuk mengenal pasti tetapi tidak dapat menyelesaikannya.

Penyelesaian

Mengendalikan ralat sedemikian bergantung pada konteks dan keperluan aplikasi khusus. Berikut adalah beberapa strategi umum yang boleh anda pertimbangkan:

1. Tingkatkan saiz timbunan:

1. Analisis penggunaan memori: Gunakan alatan seperti VisualVM, YourKit dan banyak lagi. Jadikan benang itu bodoh dan semak di mana kebocoran itu.

2. Optimumkan struktur data dan algoritma
