error: variable myS is already defined in method main(String[]) String myS = myS myString;-CodePudding

public class Main {

    public static void main(String[] args) {
        char memoryArray[] = {'a','b','c','d','e','f'};
        int s = 1;
        int l = 3;
        String myS = "";
        for (int i = s; i < s   l; i  ) {
            char tmp = memoryArray[i];
            String myString = Character.toString(tmp);
            String myS = myS   myString;
        }
    }
}

hey so I tried doing everything, the gist of my code is to transform these characters into a string that you can add, now the original code is much more complicated but I gave an oversimplified code to find out why this error is happening, if someone can please explain why?

CodePudding user response：

You need to change the code as shown below

String myS = myS   myString;

myS = myS   myString;

you cannot declare variable with same name again in same method
