Thread: Searching with keywords in a sentence

Hi everyone...
My question is related to deleting some unwanted words in a sentence like is,am,are,has,have,had,should,would and many more like these. Basically when user inputs a sentence in search box in order to search something, then program also shows the search related to above mentioned helping verbs and resultantly shows more results. So I want to delete all these words from a sentence to keep my search fast and accurate. If I use if-else or switch then I have to mention all helping verbs, which looks very odd in program and how many words I would have to handle. Is there any good and efficient way to handle this situation?
For example:
User inputs a sentence in search box "Is there any example of delete query"
There are only 3 keywords in the sentence i.e example, delete and query.
Thanks

You mean like this.........
But look at If Condition is too long. Is it a good approach?

class removeIsAmAre{
	public static void main(String args[]){
		String sentence = "this is am are would should has have had a sentence completion";
		String[] words = sentence.split(" ");
		int lenArr=words.length;
		for(int i=0;i<lenArr;i++){
			//remove is, are, am, has, have, had, he, she, it,,him, her, his, they, would, should, a, this, that
			if(words[i].equals("a") || words[i].equals("is") || words[i].equals("this") || words[i].equals("am") || words[i].equals("are")|| words[i].equals("her") || words[i].equals("this") || words[i].equals("that") || words[i].equals("had") || words[i].equals("would") || words[i].equals("should") || words[i].equals("has") || words[i].equals("have") || words[i].equals("he") || words[i].equals("she") || words[i].equals("it") || words[i].equals("they")){
				words[i]="";
			}
		   System.out.println(words[i]);
		}
	}
}

Your if-statement is insanely large and impractical, especially if you want to compare more words. Instead, use another array or an arraylist, such as:

public class TestSentence {
    public static void main(String[] args) {
        String sentence = "this is am are would should has have had a sentence completion";
        String[] words = sentence.split(" ");
        String[] wordsToCompare = {"a", "is", "this", "am", "are", "her", "that", "had", "would", "should", "has", "have", "he", "she", "it", "they"};
        // outer loop that runs through the words array
        // nested loop that runs through the wordsToCompare array
        // compare if each element matches and do something, otherwise if they don't match, do something else
        // print
    }
}

import java.util.Arrays;
import java.util.ArrayList;
 
public class TestSentence {
    public static void main(String[] args) {
        String sentence = "this is am are would should has have had a sentence completion";
        String[] words = sentence.split(" ");
        ArrayList<String> wordsToCompareList = new ArrayList(Arrays.asList("a", "is", "this", "am", "are", "her", "that", "had", "would", "should", "has", "have", "he", "she", "it", "they"));
        // use the same logic for looping as above
