Literals in Java programming: string, boolean, integer, floating point, and character literals. Java literals are fixed values used in a program. This tutorial covers Java literals in detail.
The String class represents character strings. 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 对象代表了字符的串或序列,Java 中所有字面量的字符串都是 String 的...
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...

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: ...
