It is not required that if two objects are unequal according to theequals(java.lang.Object)method, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may...

java 双等于 java等于号与equals,首先“==”是运算符号,比较的是“==”两边变量的值;equals是Object类的一个方法,Object是所有类的父类,所以所有类都可以使用equals方法,在没有被重写的情况下,equals方法是用来比较两个对象的引用是否相等,即是否指向同一个对象。下
The equals method implements an equivalence relation on non-null object references: <ul> <li>It is reflexive: for any non-null reference value x, x.equals(x) should return true. <li>It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and ...
