Chúng tôi sẽ bắt đầu với các loại nguyên thủy như số nguyên và các loại đối tượng phổ biến chẳng hạn như các chuỗi và mảng. Chúng tôi sẽ trì hoãn việc điều trị đầy đủ của các đối tượng tùy ý đến chương kế tiếp,chẳng hạn như CallNonvirtualVoidMethod, | bugs Pick a random sampling from the fests that are failing lake a random sample of lilt- Irsts dial an- failing and I lo fix just ihoM-tests.
