How to remove the middle word from a string in Java

Answer 1

import java.util.Arrays;
import java.util.stream.Collectors;
import java.util.stream.IntStream;

public class RemoveMiddleWord {
    public static void main(String[] args) {
        String str = "c# c c++ java rust";

        String result = removeMiddleWord(str);

        System.out.println(result);  // c# c java rust
    }

    public static String removeMiddleWord(String input) {
        String[] words = input.trim().split("\\s+");

        if (words.length <= 2) {
            return input; // nothing to remove
        }

        int mid = words.length / 2;

        return IntStream.range(0, words.length)
                .filter(i -> i != mid)
                .mapToObj(i -> words[i])
                .collect(Collectors.joining(" "));
    }
}
