5. Conclusion In this article, we learned how easy it is to convert aListto aStringusing different techniques. As always, the full source code for this article can be foundover on GitHub.
//Convert string to byte[] byte[] bytes = string.getBytes(); Base64 class in Java 8 Base64.getDecoder().decode() method converts a string to byte array. //String String string = "Java Tutorials"; //Base64 Decoded byte[] bytes = Base64.getDecoder().decode(string); ...

is the worst way to convert char to string because internally it’s done by constructor to convert char array to string. This is the recommended way. String valueOf method is overloaded and there is one that accepts character array. Internally this method calls the String constructor, so it’...
@Test public void givenBinaryString_whenParsingInt_shouldConvertToInt() { String givenString = "101010"; int result = Integer.parseInt(givenString, 2); assertThat(result).isEqualTo(42); } Naturally, it’s also possible to use this method with any other radix such as 16 (hexadecimal) or ...
