Data Types manipulation Java

Question

Are character immutable in java. If so, is there a way to change, update or read multiple char values in a single char variable.

String go = "djlfa";
Scanner sc = new Scanner(go);

for(int i = 0; i < go.length(); i++){
    
    Character sym = new Character(sc.next().charAt(i));
    System.out.print(sym);
}

Answer 1

So you're trying to put the string go into the wrapper type Character ? If so: Character can only store a single character - not 5 ( djlfa ) as you want to do it.

Answer 2

Are character immutable in java

Yes, there is no method to change the value of an existing Character instance without calling the constructor again.

No, this is whatString s are for. They are also immutable .
