用Java创建对象 [英] create objects in java

问题描述

我们可以通过多种方式在java ..中创建对象.
请解释.....

In how many ways we can create objects in java..?
plz explain .....

推荐答案

有多少种方法?

有一种方法:

How many ways?

There is one way:

Object object = new Object();

否则，该对象需要由另一部分给定.
可以将对象/对象副本作为参数移交:

Otherwise the Object needs to be given by another part.
One can hand over Objects/Copies of Objects as arguments:

public void method(Object object){
  // doany();
}

但是后来对象就在ohter方法中了.

有时在创建对象的位置以及出现原因/方式方面不直接可见.
使用框架时经常会发生这种情况.春天例如具有通过XML定义创建"对象的机制.

编辑:您阅读过吗? 创建对象-Java教程 [

But then the Object has been there in the ohter method.

It''s sometimes not directly visible where an Object is created and why/how it is coming up.
That''s often happening when using a framework. Spring e.g. has a mechanism to "create" Objects by a XML definition.
