问题描述：
String s1 =hello; s1 =helloworldsop（s1）如果s1在java中是不可变的，s1值将如何变化
我想要上面的答案详细解释
String s1= "hello" ; s1="helloworld" sop(s1) how s1 value will be change if s1 is immutable in java
I want above answer with details explanation
答
变量s1不是不可变的;你可以随时将这个变量重新生成一个新的字符串。
字符串hello和helloworld是不可变的;但你在你的问题中反驳了字符串和变量。
The variable s1 is not immutable; you can reaffect this variable to a new string anytime you want.
The strings "hello" and "helloworld" are immutable; but you counfound the string and the variable in your question.
