How to initialize byte array of 100 bytes in java with all 0's. I want to create 100 byte array and initialize it with all 0's
如何在java中用全0初始化100字节的字节数组。我想创建 100 字节的数组并用全 0 初始化它

A new byte array will automatically be initialized with all zeroes. You don't have to do anything.
一个新的字节数组将自动用全零初始化。你不必做任何事情。
The more general approach to initializing with other values, is to use the Arraysclass.
使用其他值初始化的更通用方法是使用Arrays类。
import java.util.Arrays;
byte[] bytes = new byte[100];
Arrays.fill( bytes, (byte) 1 );

Simply create it as new byte[100]it will be initialized with 0 by default
只需创建它，因为new byte[100]默认情况下它会被初始化为 0

回答by c.P.u1
byte[] bytes = new byte[100];
Initializes all byte elements with default values, which for byte is 0. In fact, all elements of an array when constructed, are initialized with default values for the array element's type.
使用默认值初始化所有字节元素，字节为 0。实际上，数组的所有元素在构造时都使用数组元素类型的默认值进行初始化。

Actually the default value of byte is 0.
实际上，byte 的默认值是 0。
回答by user207421
The default element value of any array of primitives is already zero: falsefor booleans.
任何基元数组的默认元素值已经为零：false对于布尔值。
