class Employee
{
public Employee(String n,double s)
{
name=n;
salary=s;
System.out.println("two parameters 222");
}
public Employee(double s)
{
this("Employee#"+nextld,s);
System.out.println("one parameter 111");
}
public Employee()
{
System.out.println("no parameter 000");
}
public String getName()
{
return name;
}
public double getSalary()
{
return salary;
}
public int getId()
{
return id;
}
private String name="";
private double salary;
private int id;
private static int nextId;
{
System.out.println("initalization");
nextId++;
}
static
{
System.out.println("static initalization");
Random generator=new Random();
nextId=generator.nextInt(10000);
}
}
public class ConstructorTest
{
public static void main(String args[])
{
Employee[] staff=new Employee[3];
staff[0]=new Employee("Harry",40000);
staff[1]=new Employee(60000);
staff[2]=new Employee();
}
for(int i=0;i<staff.length;i++)
{
Employee e=staff[i];
System.out.println("name="+e.getName()+",id="+e.getId()+",salary="+e.getSalary());
}

}
那位高手帮忙看看是哪的毛病，先谢过了

this("Employee#"+nextld,s);其中nextld应该写成nextId;
Random generator=new Random(); 在程序开头插入：import java.util.*;

"}
for(int i=0;i<staff.length;i++)
{
Employee e=staff[i];
System.out.println("name="+e.getName()+",id="+e.getId()+",salary="+e.getSalary());
}"这段代码开头的“}”是否写错？应该写成：

for(int i=0;i<staff.length;i++)
{
Employee e=staff[i];
System.out.println("name="+e.getName()+",id="+e.getId()+",salary="+e.getSalary());
}
}
