The toString() method of StringBuffer class is the inbuilt method used to returns a string representing the data contained by StringBuffer Object. A new String object is created and initialized to get the character sequence from this StringBuffer object and then String is returned by toString(). Subsequent changes to this sequence contained by Object do not affect the contents of the String.
Syntax:
public abstract String toString()
Return Value: This method returns the String representing the data contained by StringBuffer Object.
Below programs illustrate the StringBuffer.toString() method:
Example 1:
// Java program to demonstrate// the toString() Method.  class GFG {    public static void main(String[] args)    {          // create a StringBuffer object        // with a String pass as parameter        StringBuffer str            = new StringBuffer("GeeksForGeeks");          // print string        System.out.println("String contains = "                           + str.toString());    }} |
Output:
String contains = GeeksForGeeks
Example 2:
// Java program to demonstrate// the toString() Method.  class GFG {    public static void main(String[] args)    {          // create a StringBuffer object        // with a String pass as parameter        StringBuffer str            = new StringBuffer(                "Geeks for Geeks contribute");          // print string        System.out.println("String contains = "                           + str.toString());    }} |
Output:
String contains = Geeks for Geeks contribute
