步骤1:创建一个新的 Java 类 在这一步中,我们创建了一个新的 Java 类TwoObjects,该类用于定义需要返回的两个对象和相应的 Getter 方法。 步骤2:定义需要返回的两个对象 在TwoObjects类中,我们定义了两个私有属性object1和object2,它们分别表示需要返回的两个对象。我们还提供了一个构造方法TwoObjects(String obj...
If two objects are equal according to theequals(Object)method, then calling thehashCodemethod on each of the two objects must produce the same integer result. It isnotrequired that if two objects are unequal according to theequals(java.lang.Object)method, then calling thehashCodemethod on each ...
