在java中，我需要随机删除字符串中的一半单词。

import java.util.Arrays;
import java.util.Random;

public class RandomWordRemoval {
    public static void main(String[] args) {
        String sentence = "This is a sample sentence for random word removal";
        String[] words = sentence.split(" ");

        int removeCount = words.length / 2;
        Random random = new Random();

        for (int i = 0; i < removeCount; i++) {
            int indexToRemove = random.nextInt(words.length);
            words = removeElement(words, indexToRemove);
        }

        String result = String.join(" ", words);
        System.out.println(result);
    }

    private static String[] removeElement(String[] array, int index) {
        String[] newArray = new String[array.length - 1];
        System.arraycopy(array, 0, newArray, 0, index);
        System.arraycopy(array, index + 1, newArray, index, array.length - index - 1);
        return newArray;
    }
}
