How do I fix the code?

 public class MidtermProblems {
    // Main driver method
    public static void main(String args[]){
       System.out.println( "JOHN".isBlank() ); //it returns false

        System.out.println( "ROBERT".isBlank() ); //it returs false

        System.out.println( " ".isBlank() ); //it returns false
        
        System.out.println( "".isBlank() ); //it returns true
    
    int a;
    int b;
    if(s = null){
    Double a = scan.nextDouble();
    }
    else{
    Double a = scan.nextDouble();
    }
    Double b = scan.nextDouble();
System.out.println(Str. replace('line', 'userInput'));
    }

}

### Source Code Error Analysis: Common Java Compilation Errors This illustration shows a series of Java compilation errors encountered in the file `MidtermProblems.java`. Below, we’ll explain each type of error, helping you to understand and debug them effectively. #### Error Details 1. **Unclosed Character Literal Error:** - **Description:** This error indicates that there is a character literal that hasn't been properly closed. In Java, character literals should be enclosed in single quotes, e.g., `'a'`. - **Example from Code:** - `System.out.println(Str.replace('line', 'usrInput'));` - **Possible Cause:** Single quotes are used here, but the method `replace` expects two `char` arguments, not the `String` types indicated by the use of `'line'` and `'usrInput'`. 2. **Not a Statement Error:** - **Description:** This error suggests that the Java compiler was expecting a valid statement but did not find one. - **Example from Code:** - Same line: `System.out.println(Str.replace('line', 'usrInput'));` - **Analysis:** This likely stems from misuse of literals and method signatures. The `replace` method is expected to replace characters or strings properly defined. 3. **Reached End of File While Parsing:** - **Description:** This error occurs if the file ends unexpectedly without a proper closure of statements or blocks. - **Example from Code:** - The error at the last line: - **Advice:** Ensure all opening braces `{` have corresponding closing braces `}`. #### Troubleshooting Steps - **Check Character and String Literals:** Ensure that string literals are enclosed in double quotes, e.g., `"line"`, whereas character literals are enclosed in single quotes, e.g., `'l'`. - **Method Signature Verification:** Verify that methods are called with the correct parameter types. For `String.replace`, use: ```java String s = "line of text"; System.out.println(s.replace("line", "usrInput")); ``` - **Block Closure:** Examine code for any unclosed blocks and correct them by ensuring each `{` has a corresponding `}`. By understanding the nature of these errors, you can adjust your code to meet the Java language syntax requirements and eliminate compilation issues effectively.
