How to remove nul characters (\0) from string in Java

Question

I understand that this code in C# is trying to remove nul characters ( \\0 ) from a string.

string.Join("", mText.Split(new string[] { "\0" }, StringSplitOptions.None));

Is there any way to do that efficiently in Java?

Answer 1

你可以写：

mText.replace("\0", "");

Answer 2

In Java 8+ you could use StringJoiner and a lambda expression like

String str = "abc\0def";
StringJoiner joiner = new StringJoiner("");
Stream.of(str.split("\0")).forEach(joiner::add);
System.out.println(str);
System.out.println(joiner);

Output is

abc
abcdef
