1. 是一个方法,而非运算符 2. 只能适用于引用数据类型 3. Object类中equals()的定义: publicbooleanequals(Object obj) {return(this==obj); } 说明:Object类中定义的equals()和==的作用是相同的:比较两个对象的地址值是否相同.即两个引用是否指向同一个对象实体 4. 像String、Date、File、包装类等都重写...
接口不能提供对Object类的任何方法的默认实现。简单地讲,每一个java类都是Object的子类,也都继承了它类中的equals()/hashCode()/toString()方法,那么在类的接口上包含这些默认方法是没有意义的,它们也从来不会被编译。 在JVM中,默认方法的实现是非常高效的,并且通过字节码指令为方法调用提供了支持。默认方法允许继...

An operator takes one or more argument and produces a new value. The arguements are in a different form than ordinary method calls, but the effect is the same. + : addition and unary plus (another mean:string concatenation 这算不算Operators?) ...
