StringBuffer是Java中的类,定义了一个addStr()方法,并把sb对象,传入到方法中去,并且成功的改变了sb的值,这就说明进入方法体后,方法体中的局部变量sb指向了存放“Hello”的对象内存去了,不管这个指向是引用还是指针,起码引用传递能够改变原先变量sb的值嘛。
其实 类似的String,Integer,Float,Double,Short,Byte,Long,Character等等基本包装类型类。因为他们本身没有提供方法去改变内部的值,例如Integer内部有一个value来记录int基本类型的值,但是没有提供修改它的方法,而且 也是final类型的,无法通过常规手段更改。 所以虽然他们是引用类型的,但是我们可以认为它是值传递,这个也...

Given a string text, we are allowed to swap two of the characters in the string. Find the length of the longest substring with repeated character
Swap Two Characters in a Java String One of the string value’s main properties is that it is immutable, meaning it cannot be changed. To perform the swap operation, we first have to copy theStringobject to aStringBuilderor a character array. These two data types allow us to perform swap...

Given a binary string s, return the minimum number of character swaps to make it alternating, or -1 if it is impossible.The string is called alternating if no two adjacent characters are equal. For example, the strings "010" and "1010" are alternating, while the string "0100" is not....
