Choose fields to be included in hashCode() Select the fields to generate hash code. Note that only the fields that were included in the equals() method can participate in creating hash code. All these fields are
public class PrimitiveClass { private boolean primitiveBoolean; private int primitiveInt; // constructor, getters and setters } We use the Eclipse IDE to generateequals() andhashCode() using ‘Source->GeneratehashCode()andequals()‘. Eclipse provides a dialog box like this: ...
意识就是:这个类中没有非静态值.无法创建equals方法和hashcode方法. 当test类加了int a 后 当你添加完非静态的成员变量时,再在eclipse中自动生成重写equals()和hashcode()后. 这时类调用equals就不是Object中的比较地址了,而是比较两者的内容.
以生成Getter/Setter为例:选中类字段后按Alt+Insert,选择'Getter and Setter',IDE会智能识别字段类型并生成符合JavaBean规范的代码,避免手动编码可能出现的拼写错误。 二、equals()与hashCode()生成实践 当需要实现对象相等性判断时,手动编写equals()和hashCode()容易遗漏null检查或字段比对。...
