error: incompatible types: java.lang.String cannot be converted to String

Question

I\'m taking a Java class for college, and was working on some given tasks. This is the code I wrote for it.

public class String
{
 public static void main(String         


        

Answer 1

It is conflict between system class java.lang.String and your class named String. Rename your class String to say MyString, i.e. replace line:

public class String

with

public class MyString

And rename file String.java containing this class to MyString.java.

Answer 2

You can't name your class String because that is a reserved word similar to double or else.

Here is a list of reserved Java keywords: https://en.wikipedia.org/wiki/List_of_Java_keywords

Answer 3

Since your class is named String, unqualified type reference in String city is taken as reference to your own class.

Either rename the class to some other name, or you'll have to write java.lang.String wherever you reference the "built-in" Java String class.
