A new byte array will automatically be initialized with all zeroes. You don't have to do anything. The more general approach to initializing with other values, is to use the Arrays class.

APIzation

import java.util.Arrays;

byte[] bytes = new byte[100];
Arrays.fill( bytes, (byte) 1 );

package com.stackoverflow.api;

import java.util.Arrays;

public class Human16475547 {

  public static byte[] initializeByteArray() {
    byte[] bytes = new byte[100];
    Arrays.fill(bytes, (byte) 1);
    return bytes;
  }
}

package com.stackoverflow.api;

import java.util.Arrays;
