Question
Compile MessageSolution.java:22: error: cannot find symbol if (n == Integer.parseInt(s)) { ^ symbol: variable s location: class Solution1 error
Solution
The error message you're seeing is because the Java compiler cannot find the symbol 's'. This means that the variable 's' has not been declared in the scope you're trying to use it in.
Here's how you can fix it:
-
Check where you have declared the variable 's'. It should be in the same method or class where you're trying to use it. If it's not, you need to declare it.
-
If 's' is a parameter being passed into the method, make sure that you have correctly spelled and capitalized the variable name. Java is case-sensitive.
-
If 's' is supposed to be a class variable and you're trying to use it in a static context, this could be causing the issue. Non-static class variables cannot be referenced from a static context.
-
If 's' is a variable from another class, make sure to reference it correctly. You might need to use the class name, like
ClassName.s.
Without seeing your code, it's hard to give a more specific solution. But the error message is saying that 's' has not been declared in the scope you're trying to use it in.
