一.Java基础面试题1.谈谈你对面向对象的理解 对比面向过程,是两种不同处理问题的角度,面向过程更注重事情的每一步骤及顺序,面向对象更注重事情有哪些参与者(对象),以及各自需要做什么。面向过程比较直接高效,面向对象易于复用、扩展和维护。
|
|
|
|
|
面向对象的三大基本特征:封装、继承、多态(父类应用指向子类对象)
|
|
|
|
|
2.JDK、JRE、JVM之间的区别JDK java 开发工具
|
|
|
|
|
JRE(Java Runtime Environment Java 运行环境)
|
|
|
|
|
JVM java虚拟机
|
|
|
|
|
JDK = JRE + 开发工具集(例如 Javac,java 编译工具等)
|
|
|
|
|
JRE = JVM + Java SE 标准类库(java 核心类库)
