publicfinalclassStringimplementsjava.io.Serializable,Comparable<String>,CharSequence{/** The value is used for character storage. */privatefinal char value[];/** Cache the hash code for the string */privateint hash;// Default to 0...} 从上面的源码可以看出: String类被final关键字修饰,意味着S...
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 buffers support mutable strings. Because String objects are immutable ...
