我正在尝试测试一个程序,为此我需要访问ReadExternal函数,但我在ObjectInputStream上得到StreamCorrupted异常.我知道我需要使用WriteObject编写的对象,但不知道该怎么做...

ObjectOutputStream out=new ObjectOutputStream(new ByteArrayOutputStream());
    out.writeObject(ss3); 
    ss3.writeExternal(out);
    try{
         ByteInputStream bi=new ByteInputStream();
         bi.setBuf(bb);
         out.write(bb);
         ObjectInputStream in = new ObjectInputStream(new ByteArrayInputStream(bb));
         String s1=(String) in.readObject();
        }
        catch(Exception e){
            e.printStackTrace();
        }

我编写了以下程序和程序抛出编译错误

我不知道为什么会出现错误,因为所有的分号和括号似乎都已到位

import java.io.*;

public class Solution {
  public static void main(String args[]) throws Exception {
    long coords[5000][2];
    long number;
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

    try {
      number = Long.parseLong(br.readline());  // take no of inputs
      //take all co ordinates and store it in 2d array
      for(long i=0;i<number;i++) {  
        coords[i][0] = Long.parseLong(br.readline());
        coords[i][1] = Long.parseLong(br.readline());
      }
    } catch(NumberFormatException e) {
      System.out.println("Number Format Exception:");
    }

    if(check_line(coords,number)) {
      System.out.println("YES");
    } else {
      System.out.println("NO");
    }
  }

  public boolean check_line(long coords[][], long limit) { …
