staticmember.java

这个是学习网络编程的好好文档！ 里面有一些老师发给的学习jsp的课件！

public class StaticMember
{
  static int count = 0;
  int num;
  
  public StaticMember()
  {
    count++;
    num=count;
  }
  
  public static int getNum()
  {
    // return num; //Cannot access non-static variable in static method
    return count;
  }  
}

class Test
{
  public static void main(String args[])
  {
    StaticMember s1 = new StaticMember();
    System.out.println("StaticMember.count="+StaticMember.count);
    StaticMember s2 = new StaticMember();
    System.out.println("StaticMember.count="+StaticMember.count);
    StaticMember s3 = new StaticMember();
    System.out.println("StaticMember.count="+StaticMember.count);
    
    System.out.println("S1.count="+s1.count+",S1.num="+s1.num);
    System.out.println("S2.count="+s2.count+",S2.num="+s2.num);
    System.out.println("S3.count="+s3.count+",S3.num="+s3.num);
  }
}
