String可以说是Java中使用最多最频繁、最特殊的类,因为同时也是字面常量,而字面常量包括基本类型、String类型、空类型。 一. String的使用 1. String的不可变性 /** * The {@codeString} class represents character strings. All * string literals in Java programs, such as {@code"abc"}, are * implement...
Java Character Literals Character literals are enclosed in single quotes when they are used for example, 'a' or 'A'. Whereas string literals are enclosed in double quotes for example, "Coffea arabica". charcharLit='a';StringstrLit="String Literal"; ...
All string literals in Java programs, such as "abc", are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String ...

String Literals(Java语言规范Java LanguageSpecifications) The program consisting of the compilation unit : package testPackage; class Test { public static void main(String[] args) { String hello = "Hello", lo = "lo"; System.out.print((hello == "Hello") + " "); ...
* Because String objects are immutable they can be shared. For example: {@code String}类表示字符串。所有java程序中的字符文字,例如{@code "abc"},是作为此类的实例实现。 The {@code String}classrepresents character strings. All* string literals in Java programs, such as {@code "abc"}, are*...

String Literals The most basic form of pattern matching supported by this API is the match of a string literal. For example, if the regular expression is foo and the input string is foo, the match will succeed because the strings are identical. Try this out with the test harness: ...
