类中的equals(Object obj)方法体Object是:

public boolean equals(Object obj) {
    return (this == obj);

并hashCode()是native:

public native int hashCode();

我有一个类Test有overrided equals(Object obj)和hashCoe():

public class Test {

public static void main(String[] args){
    Test t1 = new Test();
    Test t2 = new Test();

    System.out.println("t1 toString() : " + t1.toString());
    System.out.println("t1, Hex value of hashcode : " + Integer.toHexString(t1.hashCode()));
    System.out.println("t2 toString() : " + …
