Which of this method of class string is used to extract a substring from a string object Mcq?1. Which of these methods of class StringBuffer is used to extract a substring from a String object? Explanation: None.
Which of these methods of class StringBuffer is used to extract a substring from a string object in Java?The substring(int start) method of StringBuffer class is the inbuilt method used to return a substring start from index start and extends to end of this sequence. The string returned by this method contains all character from index start to end of the old sequence.
Which method is used to extract a part of a string?The substr() method extracts a part of a string. The substr() method begins at a specified position, and returns a specified number of characters.
