如何在考虑到EOF不足的情况下读取Java中的标准输入？

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        while (scanner.hasNext()) {
            String line = scanner.nextLine();
            // 处理输入
        }
        scanner.close();
    }
}

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
    public static void main(String[] args) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String line;
        try {
            while ((line = reader.readLine()) != null) {
                // 处理输入
            }
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        try {
            int data;
            while ((data = System.in.read()) != -1) {
                // 处理输入
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
