读入一系列数 统计正负数个数 读入0终止  好麻烦感觉 JAVA新手 我自己写的运行不了 下面哪里错了
Exception in thread "main" java.lang.Error: 无法解析的编译问题：

    at count.main(count.java:5)    at count.main(count.java:7)
import javax.swing.JOptionPane;
public class count {

   
    public static void main (String args[])
   
    {
        int len;
        int Array[];
        Array = new int[len];
        String input;
        int Positive=0;
        int Negative=0;
        int i ;
        String number1;
        number1= JOptionPane.showInputDialog("请输入你要输入整数的个数");
        len=Integer.parseInt(number1);
        
        for ( i=0 ; i<len; i++ )
        {
            input = JOptionPane.showInputDialog(Array);
            int number = Integer.parseInt(input);
            
            if (number>0)
            
            
                Positive++;
                else if (number<0)
               
                    
                    Negative++;
            
                else if(number==0)
                    break ;
               
               
            }
        JOptionPane.showMessageDialog(null,"正整数的个数是："+Positive+"个"+"\n"+"负整数的个数是:"+Negative+"个");
        
            
            
            
        }

    }

}

//可以输入小数，整数；例如：-0.98 9.98 9 -7

OException 神马意思 BufferedReader   BufferedReader(new InputStreamReader(System.in));
 显示错了

字符输入缓冲流，会有异常抛出，throws 抛出异常
显示错了什么意思？

public static void main (String[] args)
main入口！！！
