java - 字符串构造函数的这种实现如何工作（java）？

Question

 public String(String original) {
     int size = original.count;
     char[] originalValue = original.value;
     char[] v;
     if (originalValue.length > size) {
         // The array representing the String is bigger than the new
         // String itself.  Perhaps this constructor is being called
         // in order to trim the baggage, so make a copy of the array.
         int off = original.offset;
         v = Arrays.copyOfRange(originalValue, off, off+size);
     } else {
         // The array representing the String is the same
         // size as the String, so no point in making a copy.
         v = originalValue;
     }
     this.offset = 0;
     this.count = size;
    this.value = v;
 }

如果我是愚蠢的，我很抱歉，但我不明白。count 和 value 字段是私有的，但这段代码似乎以某种方式直接达到了这些值。怎么会这样？

private意思是“只能被类访问”，而不是“只能被对象访问”。
