java怎么将输入流传入数组

byte[] buffer = new byte[inputstream.available()];

int bytesRead = inputstream.read(buffer);

for (int i = 0; i < bytesRead; i++) {
    yourArray[i] = buffer[i];
}

import java.io.ByteArrayInputStream;
import java.io.IOException;

public class InputStreamToByteArray {

    public static void main(String[] args) throws IOException {
        // 创建一个输入流
        ByteArrayInputStream inputstream = new ByteArrayInputStream("Hello World".getBytes());

        // 创建一个字节数组
        byte[] buffer = new byte[inputstream.available()];

        // 读入输入流
        int bytesRead = inputstream.read(buffer);

        // 检查读取的字节数
        if (bytesRead == -1) {
            System.out.println("流已结束");
        }

        // 将字节复制到数组中
        byte[] yourArray = new byte[bytesRead];
        for (int i = 0; i < bytesRead; i++) {
            yourArray[i] = buffer[i];
        }

        // 转换数组为字符串并打印
        System.out.println(new String(yourArray));
    }
}

Hello World
