Java作业整理 敏感词汇

1. 敏感词汇分析（难）

要求：任意选择一个文本文件，分析该文件，如果存在敏感词汇（这些词汇保存在sentive.txt文件中，每个词占一行），报告每个词出现的次数。

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.Scanner;
public class sensitive_Vocabulary {
	
	Scanner input=new Scanner(System.in);
	public String[] ch;  
	public void write(int number) throws Exception{
		System.out.println("请输入你的敏感词汇：");
  	  ObjectOutputStream output =
  		  new ObjectOutputStream(new FileOutputStream("sensitive.txt"));      
  	  for(int i = 0; i < number;i++){
  		 String str = input.nextLine();
  		 output.writeUTF(str);
  	  }
  	  
  	output.close(); 
    }
	public void readObject(int number) throws Exception{
		ObjectInputStream input = 
			new ObjectInputStream(new FileInputStream("sensitive.txt"));
		       ch = new String[number];
			for(int j = 0; j < number; j++){
		     ch[j] = input.readUTF();
		   //  System.out.println("敏感词汇为："+ch[j]);
			}
		   	   input.close();
            }		
}
