从文本文件 java 中读取某些单词

Question

So i have a text file ( tagged.txt ) full of different sentences. What I am looking to do is read this text file into Java, and extract specific words from this file.

eg

Sentence : I went to the shop to buy a new pair of trainers

If the sentence has the words shop , buy , or trainers in it, I would like that sentence to equal an opinion.

I have created a list of the words in a text file ( words.txt ), in which I would like to stream against the tagged.txt file.

I just wanted to know if there is a way of implementing this in Java.

Answer 1

• Read the words from words.txt and store in an array and sort it using Arrays.sort(arr) .
• Read the lines from tagged.txt line by line and store it in a String . Then you could use split() to split the line into different words and store the words in an array.
• Then loop through the words of the line, and use the array's binarysearch method to search through the words from the words array.
