  • Q1. Which 2 methods must an object implement in order to be used as a key in hasmap and why
  • Ans. 

    The object must implement the hashCode() and equals() methods to be used as a key in a hashmap.

  • Q2. Is it preferable to use stringBuffer with its synchronized methods or stringBuilder when implementing toString() method? why?
  • Ans. 

    Use stringBuilder for toString() method as it is faster and not thread-safe.

    • stringBuilder is faster than stringBuffer as it is not thread-safe

    • toString() method is used for converting an object to a string

    • If thread-safety is required, use stringBuffer instead

    • Example: StringBuilder sb = new StringBuilder(); sb.append("Hello"); sb.append("World"); return sb.toString();

  • Q4. Is it good idea to wrap java.io.FileInputStream and java.io.FileOutputStream in buffered writers and readers and why?
  • Ans. 

    Yes, it is a good idea to wrap FileInputStream and FileOutputStream in buffered writers and readers.

    • Buffered streams improve performance by reducing the number of I/O operations

    • Buffered streams also provide additional functionality like readLine() and newLine()

    • Buffered streams can be chained together for even better performance

    • Example: BufferedReader br = new BufferedReader(new FileReader(file));
