How do you encode a character in Java?
Encoding With Core Java
Strings are immutable in Java, which means we cannot change a String character encoding. To achieve what we want, we need to copy the bytes of the String and then create a new one with the desired encoding.
Does Java use UTF-8 or UTF-16?
UTF-8 uses one byte to represent code points from 0-127, making the first 128 code points a one-to-one map with ASCII characters, so UTF-8 is backward-compatible with ASCII. Note: Java encodes all Strings into UTF-16, which uses a minimum of two bytes to store code points.
How do I change encoding type?

What are the two most popular character encoding?
The most common ones being windows 1252 and Latin-1 (ISO-8859).
Which character set does Java uses?
Internally, Java uses the Unicode character set. Unicode is a two-byte extension of the one-byte ISO Latin-1 character set, which in turn is an eight-bit superset of the seven-bit ASCII character set.
What is the point of UTF-16?
UTF-16 allows all of the basic multilingual plane (BMP) to be represented as single code units. Unicode code points beyond U+FFFF are represented by surrogate pairs. The interesting thing is that Java and Windows (and other systems that use UTF-16) all operate at the code unit level, not the Unicode code point level.
What is the purpose of UTF-8?
UTF-8 is the most widely used way to represent Unicode text in web pages, and you should always use UTF-8 when creating your web pages and databases. But, in principle, UTF-8 is only one of the possible ways of encoding Unicode characters.
Why do we use UTF-8?
A Unicode-based encoding such as UTF-8 can support many languages and can accommodate pages and forms in any mixture of those languages. Its use also eliminates the need for server-side logic to individually determine the character encoding for each page served or each incoming form submission.
What comes first encoding or decoding?
In order to read, you need to decode (sound out) words. In order to spell, you need to encode words. In other words, pull the sounds apart within a word and match letters to the sounds.
