java in the class declaration of variables Why is placed in a class rather than at the end of the beginning

Such as title, learn C language is always the first to declare variables , to the JAVA program I saw the book are the variable declaration at the end of the class , and why ?
as

import java.util.*;
  
  public class Test
  {
  	public static void main(String[] args)
  	{
  			
  	}	
  }
  
  abstract class Person
  {
  	// Private String name;  为什么不放在开头处？
  	
  	public Person(String n)	
  	{
  			name = n;
  	}
  	
     Private String name;
  }
