可以看出String属于对象类型,其在实际中是以字符数组的方式进行存储的即value[],其用final修饰也就意味着着一旦赋值不可改变,这也是为什么String的值不可改变的原因,正式因为其值不可变在计算hash的时候进行一个hash为0的判断,如果不为零说明已经计算过就不需要重新计算了。hash值用于映射该字符串,方便进行缓存 /**...

In .NET Framework desktop apps, you can use the<UseRandomizedStringHashAlgorithm> elementto generate unique hash codes on a per-application domain basis. This can reduce the number of collisions and improve the overall performance of insertions and lookups that use hash tables. The following exampl...
Returns the hash code for this string using the specified rules. GetPinnableReference() Returns a reference to the element of the string at index zero. This method is intended to support .NET compilers and is not intended to be called by user code. GetType() Gets the Type of the curr...
compareToIgnoreCase()方法实现:String在内部自定义了一个名为CaseInsensitiveComparator的类,实现Comparator,用来比较忽略大小写的两个字符串,比较逻辑是,依次取出两个字符进行忽略大小写的比较,其余逻辑和上面类似。 hashCode()方法返回String的hash值。 3. startWith()、endWith() ...
