  • Q2. Difference between put and patch
  • Ans. 

    Put is used to create or replace a resource, while patch is used to update a resource partially.

    • Put requires the client to send the entire updated resource, while patch only requires the specific changes to be sent

  • Q3. Difference between == and equals in string
  • Ans. 

    The == operator checks for reference equality, while the equals method checks for value equality in strings.

    • Use == to check if two string variables refer to the same object in memory.

    • Use equals() method to check if two string variables have the same sequence of characters.

    • Example: String str1 = "hello"; String str2 = "hello"; str1 == str2 will return false, but str1.equals(str2) will return true.

  • Answered by AI
  • Q4. Difference way of declaring String

    String can be declared using double quotes, single quotes, or the String constructor.
