Deleting word inside text file

I amdeveloping a command line application to filter a text file by deleting the words specified by the user via the command line.
when the code finds the filter word inside the line its deleting the whole line not just the word.
Is there a way to split the line into separate words?

public class Main11 {

    public static void main(String[] args) {

        Scanner s=new Scanner (System.in);

        System.out.println("<Source file> <Words to filter>");

        String st1=s.nextLine();

        String [] split1=st1.split(" ");

        Path p = Paths.get(split1[0]);


        try {

            List<String> lines=Files.readAllLines(p, StandardCharsets.UTF_8);
            List<String> filter = lines;


            for(int i=0;i<lines.size();i++) {

                for(int j=0;j<split1.length;j++) {



                    final int x=j;

                    filter=filter.stream().filter(line-> !line.contains(split1[x])).collect(Collectors.toList());

                }
            }

            BufferedWriter writer = Files.newBufferedWriter(p);

            for(int c=0;c<filter.size();c++) {
                writer.write("\n" + filter.get(c));
            }

            writer.close();

            System.out.println("Done");

        } catch (IOException e) {

            System.out.println("file not found");
        }

        s.close();

    }

}

>Solution :

Maybe you could store the words to be filtered in a Set:

import java.io.BufferedWriter;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Scanner;
import java.util.Set;
import java.util.stream.Collectors;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter: <source-file> <words-to-filter>");
        String input = scanner.nextLine();
        String[] inputSplit = input.split(" ");
        String sourceFile = inputSplit[0];
        Path p = Paths.get(sourceFile);
        Set<String> wordsToFilter = Set.of(Arrays.copyOfRange(inputSplit, 1, inputSplit.length));
        try {
            List<String> lines = Files.readAllLines(p, StandardCharsets.UTF_8);
            List<String> filteredLines = new ArrayList<>(lines.size());
            for (String line : lines) {
                filteredLines.add(Arrays.stream(line.split(" "))
                    .filter(word -> !wordsToFilter.contains(word))
                    .collect(Collectors.joining(" ")));
            }
            BufferedWriter writer = Files.newBufferedWriter(p);
            for (String filteredLine : filteredLines) {
                if (!filteredLine.isEmpty()) {
                    writer.write(filteredLine + "\n");
                }
            }
            writer.close();
            System.out.println("Done filtering!");
        } catch (IOException e) {
            System.err.println("Error: file not found");
        }
    }

}

Example Usage:

Enter: <source-file> <words-to-filter>
/Users/shash/Desktop/file.txt a c
Done filtering!

file.txt before:

a a a
a a a b a c d a
b b b d e r

file.txt after:

b d
b b b d e r
