        StringBuffer sb =
			new StringBuffer("We are comparing the content with a StringBuffer content");
        /**
         * We can use contentEquals() method to compare content with a StringBuffer.
         * It returns boolean value.
         */
        if(c.contentEquals(sb)){
            System.out.println("The content is equal");
        } else {
            System.out.println("The content is not equal");
        }
        StringBuffer asb =
			new StringBuffer("You cannot compare the content with a String content");
        if(c.contentEquals(asb)){
            System.out.println("The content is equal");
        } else {

Transient and Volatile Modifiers
Transient: The transient modifier applies to variables only and it is not stored as part of its object's Persistent state. Transient variables are not serialized.

Volatile: Volatile modifier applies to variables only and it tells the compiler that the variable modified by volatile can be changed unexpectedly by other parts of the program.
