关于StringBuilder

Question

请问既然说StringBuilder定义的字符串是变量那么请问应该如何修改？

StringBuilder one=new StringBuilder("wang");//创建了一个StringBuilder类型的字符串wang。
//请问这里定义的one是一个变量字符串。我应该如何去修改他的值？
StringBuilder one=new StringBuilder("zhang");;//这是编译器会报错 复制本地变量的one

请问大家我既然定义了StringBuilder类型 肯定是要做很多次修改字符串的

那么请问应该如何去具体修改？
