Java : StandardCharsets with Examples
Published : January 9, 2023
StandardCharsets (Java SE 19 & JDK 19) API Examples.
You will find code examples on most StandardCharsets methods.
Summary
Constant definitions for the standard charsets. These charsets are guaranteed to be available on every implementation of the Java platform.
final var utf8 = StandardCharsets.UTF_8;
System.out.println(utf8); // UTF-8
final var utf16 = StandardCharsets.UTF_16;
System.out.println(utf16); // UTF-16
final var text = "abc♪";
System.out.println(text); // abc♪
final var encoded1 = text.getBytes(utf8);
System.out.println(Arrays.toString(encoded1)); // [97, 98, 99, -30, -103, -86]
final var encoded2 = text.getBytes(utf16);
System.out.println(Arrays.toString(encoded2)); // [-2, -1, 0, 97, 0, 98, 0, 99, 38, 106]
Fields
static final Charset ISO_8859_1
ISO Latin Alphabet No. 1, also known as ISO-LATIN-1.
final var charset = StandardCharsets.ISO_8859_1;
System.out.println(charset); // ISO-8859-1
static final Charset US_ASCII
Seven-bit ASCII, also known as ISO646-US, also known as the Basic Latin block of the Unicode character set.
final var charset = StandardCharsets.US_ASCII;
System.out.println(charset); // US-ASCII
static final Charset UTF_16
Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark.
final var charset = StandardCharsets.UTF_16;
System.out.println(charset); // UTF-16
static final Charset UTF_16BE
Sixteen-bit UCS Transformation Format, big-endian byte order.
final var charset = StandardCharsets.UTF_16BE;
System.out.println(charset); // UTF-16BE
static final Charset UTF_16LE
Sixteen-bit UCS Transformation Format, little-endian byte order.
final var charset = StandardCharsets.UTF_16LE;
System.out.println(charset); // UTF-16LE
static final Charset UTF_8
Eight-bit UCS Transformation Format.
final var charset = StandardCharsets.UTF_8;
System.out.println(charset); // UTF-8
