The absolutely most important reason that String is immutable is that it is used by the class loading mechanism, and thus have profound and fundamental security aspects. Had String been mutable, a request to load "java.io.Writer" could have been changed to load "mil.vogoon.DiskErasingWriter"...
2. What Is an Immutable Object? An immutable object is anobject whose internal state remains constant after it has been entirely created. This means that once the object has been assigned to a variable, we can neither update the reference nor mutate the internal state by any means. We have...

*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. *字符串是常量;它们的值在创建后不能更改,因为String对象是不可变的,所以它们可以共享。

String buffers support mutable strings. Because String objects are immutable they can be shared. 接下来说字符缓冲区支持可变的字符串,因为缓冲区里面的字符串对象们可以被共享(其实就是使对象的引用发生了改变)。 在Java 中,提供了通过字符串连接符( + )号,将其他类型的对象转换成 String 类型: ...
String buffers support mutable strings. Because String objects are immutable they can be shared. For example: String str = "abc"; is equivalent to: char data[] = {'a', 'b', 'c'};String str = new String(data); Here are some more examples of how strings can be used: System.out....
