Java convert byte[] to InputStream with new line after each array entry-CodePudding

Say I have a byte array like,

byte[] byteArray = { 'm', 'e', 'o', 'w'};

I'm converting this to InputStream using,

new ByteArrayInputStream(byteArray)

But I want the resultant InputStream to add a new line after each array entry like

m
e
o
w

How can I achieve this in an efficient way. The byte array could have 100s to 1000s of entries?

CodePudding user response：

The efficient way to do it would be to create another byte[]

byte[] byteArray = ...;
byte[] newBytes = new byte[byteArray.length *2];
for (int i = 0; i < byteArray.length; i  ) {
  newBytes[i*2] = byteArray[i];
  newBytes[i*2   1] = '\n';
}
