在Java中，什么时候会创建一个.class文件？
示例
class A { A() { System.out.println("This is class A"); } } class B { B() { System.out.println("This is class B"); } } class C { C() { System.out.println("This is class C"); } } public class ClassTest { public static void main(String[] args) { A obj1 = new A(); B obj2 = new B(); C obj3 = new C(); } }登录后复制
输出
This is class A This is class B This is class C登录后复制
