Object code is often compared tosource code; both play a critical role in software development. Source code is human-readable and much easier to work with than object code. For this reason, it is commonly used when first developing a softwareprogram. Developers write the code in plain text, ...
答:Object类存储在java.lang包中,是所有java类(Object类除外)的终极父类。当然,数组也继承了Object类。然而,接口是不继承Object类的,原因在这里指出:Section 9.6.3.4 of the Java Language Specification:“Object类不作为接口的父类”。 Object类中声明了以下函数,我会在下文中作详细说明。
It should be kept in mind that thetoIdentityString()is not null-safe and may throw theNullPointerExceptionso use it with care. Happy Learning !! Source Code on Github
