如果Java要打100行的代码，一般用Python要打大概多少行？

视具体代码情况而定，视是否引用外部包而定，视个人编程书写习惯而定。

具体的来说，Python可以将任意长的代码写在一行上（其实好像java也可以这么干）。

所以行数说明不了什么问题。

平均来看，Java要打100行的代码，Python大约需要50行代码左右。

另外Python在某些问题上，处理比Java要更消耗资源，不过Python用了很多多线程优化，所以说起来，单机的运行速度不相上下，但在服务器上运行就能看出来Java是有明显优势的。

用JAVA语言编写100行以上的代码，要求主要应用string类中的equal（）方法

class Person{

private String name;

private int age;

public Person(String name,int age){

this.name=name;

this.age=age;

}

public boolean equals(Object obj){

if( ! (obj instanceof Person)){

return false;

}

Person per1=this;

Person per2=(Person)obj;

boolean flag=false;

if(per1==per2){

flag=true;

}

else{

if(per1.name.equals(per2.name)per1.age==per2.age){

flag=true;

}

}

return flag;

}

public String toString(){

return "姓名："+this.name+",年龄："+this.age;

}

}

public class OODemo17{

public static void main(String []args){

Person p1=new Person("张三",23);

Person p2=new Person("张三",23);

System.out.println(p1.equals(p2));

Person p3=p2;

System.out.println(p2.equals(p3));

System.out.println(p1.equals("a string"));

}

}

输出结果：

true

true

false
