StringBuilder toString() method in Java with Examples

The toString() method of StringBuilder class is the inbuilt method used to returns a string representing the data contained by StringBuilder Object. A new String object is created and initialized to get the character sequence from this StringBuilder 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 StringBuilder Object.

Below programs illustrate the StringBuilder.toString() method:

Example 1:

// Java program to demonstrate 
// the toString() Method. 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a StringBuilder object 
        // with a String pass as parameter 
        StringBuilder str 
            = new StringBuilder("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 StringBuilder object 
        // with a String pass as parameter 
        StringBuilder str 
            = new StringBuilder( 
                "Geeks for Geeks contribute"); 
  
        // print string 
        System.out.println("String contains = "
                           + str.toString()); 
    } 
} 

Output:

String contains = Geeks for Geeks contribute
