MCQs and coding problems
duration - 1Hr 30min
(4 Questions)
- 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.
hashCode() method is used to generate a unique hash code for the object.
equals() method is used to compare two objects for equality.
Both methods are necessary for proper functioning of hashmap operations like put() and get().
- 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();
- Q3. What are 2 checklists to be executed for overriding object.equals(object args) for a class with only one instance variable
- 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));
