Solving cannot find symbol variable

When encountering the error message "cannot find symbol variable" in Java, it means that the compiler is unable to recognize a variable that has been used in the code. This can be caused by a variety of issues, such as a typo in the variable name or a missing import statement.

To solve this error, it's important to carefully review the code and ensure that all variable names are spelled correctly and match their corresponding declarations. It's also important to check for any missing import statements, as this can cause the compiler to be unable to recognize certain variables.

If the issue persists, it may be helpful to try recompiling the code or restarting the IDE. Additionally, seeking help from online forums or resources can provide further insight into the issue and potential solutions.

Example code:

public class Example {
  public static void main(String[] args) {
    int num = 5;
    System.out.println(number); // This will result in a "cannot find symbol variable" error
  }
}

In the above example, the error is caused by a typo in the variable name. Changing "number" to "num" would solve the issue.
