why strings in java when we can have array of characeter or viceversa?

[Ciary]

because an array is fixed size, and a string isn't. a string is more an arraylist of chars but appending to an arraylist requires more code than appending 2 strings together.

In Java Strings are immutable, so they technically are a fixed size. They are far more convenient and easier to use than Char[] though. Say you have String s = "hi". You can call any function on s, but as long as you don't break the reference to s you will always be able to see that s = "hi".
