这是一个在"Java Algorithms and Clients - Algorithms,第4版“的StdRandom类中生成长型随机数的方法。
public static long uniform(long n) {
if (n <= 0L) throw new IllegalArgumentException("argument must be positive: " + n);

我看到了一段代码,它覆盖equals()并相应地覆盖hashcode(),这是可以理解的。
@Override
public int hashCode() {
int result = id;
result = 31 * result + (int) (providerId ^ (providerId >>> 32));
result = 31 * result + (int) (promotionId ^ (promotionId >>> 32));
result = 31 * result + (coordinate
class MyClass {
}
public class Test {
public static void main(String[] args) {
MyClass g = new MyClass();
System.out.println(g.getClass()); //print MyClass
MyClass g2 = new MyClass(){};
System.out.println(g2.getClass()); //print Test$1
}
}
有谁能给我解释一下
