String：字符串常量，字符串长度不可变。Java中String是immutable（不可变）的。

[java] view plaincopy

/** The value is used for character storage. */  
private final char value[];  
  
/** The offset is the first index of the storage that is used. */  
private final int offset;  
  
/** The count is the number of characters in the String. */  
private final int count;
