这段代码是如何运行的？ [英] How this code is Running?

问题描述

  interface  i1  extends  Object 
 {
  void  show（）; 
} 
  class  Sigma  implements  i1 
 {
  public   void  show（）
 {
 System.out.println（  Hanosh）; 
} 
  public   String  toString（）
 {
  return    Manish; 
} 
  public   static   void  main（ String  arg []）
 {
 i1 i = new Sigma（）; 
 i.show（）; 
  String  s = i.toString（）; 
} 
} 

解决方案

我不确定这个问题的意图，但我很确定你需要开始阅读有关编程和这个特定语言的内容。



但是，让我列出程序涵盖的区域：

任何程序都通过一个名为 Main 功能的入口点启动。



http://en.wikipedia.org/wiki/Entry_point [ ^ ]



函数中的第一个语句实例化Sigma class 的新对象。



http://en.wikipedia.org/wiki / Class_（computer_programming） [ ^ ]



你还会注意到这个类实现了一个特定的界面。



http://en.wikipedia.org/wiki/Interface_(computing) [ ^ ]



这里看到的一些其他概念是静态成员和成员的访问级别（公共，私人等）



http://en.wikipedia.org/wiki/Method_(computer_programming)#Static_methods [ ^ ]



http://msdn.microsoft.com/en-us/library/ms173121.aspx [ ^ ]

这不是魔法 - 但它不是也很容易解释。从这里开始阅读： Jave教程：继承 [ ^ ]完成后，你应该有更好的主意。

interface i1 extends Object
{
	void show();
}
class Sigma implements i1
{
	public void show()
	{
		System.out.println("Hanosh");
	}
	public String toString()
	{
		return "Manish";
	}
	public static void main(String arg[])
	{
		i1 i=new Sigma();
		i.show();
		String s=i.toString();
	}
}

解决方案

I am not sure the intention of this question, but I am quite sure that you need to start reading about programming and this particular language in question.

However, let me list down the areas which program cover:
Any program starts via an Entry Point which is called as Main Function.

http://en.wikipedia.org/wiki/Entry_point[^]

The first statement in the function instantiates a new object of Sigma class.

http://en.wikipedia.org/wiki/Class_(computer_programming)[^]

What you would also notice that this class implements a particular interface.

http://en.wikipedia.org/wiki/Interface_(computing)[^]

Some other concepts which would see here are static members and the access levels of members (Public, Private etc.)

http://en.wikipedia.org/wiki/Method_(computer_programming)#Static_methods[^]

http://msdn.microsoft.com/en-us/library/ms173121.aspx[^]

It's not magic - but it's not simple to explain either. Start reading here: The Jave Tutorials: Inheritance[^] when you have finished, you should have a better idea.
