The Java.lang.StringBuffer.reverse() is an inbuilt method that is used to reverse the characters in the StringBuffer. The method causes this character sequence to be replaced by the reverse of the sequence. 

Syntax: 

public StringBuffer reverse()

Parameters: NA

Return Value: The method returns the StringBuffer after reversing the characters. 

Examples:  

Input: StringBuffer = GeeksforGeeks!
Output = !skeegrofskeeG

Input: StringBuffer = Hello World!
Output = !dlroW olleH

Below are programs that illustrate the java.lang.StringBuffer.reverse() method: 

Program 1:  

java




// Java program to illustrate the
// java.lang.StringBuffer.reverse()
import java.lang.*;
 
public class Test {
 
    public static void main(String args[])
    {
        StringBuffer sbf = new StringBuffer("Geeksforgeeks!");
        System.out.println("String buffer = " + sbf);
         
        // Here it reverses the string buffer
        sbf.reverse();
        System.out.println("String buffer after reversing = " + sbf);
    }
}


Output: 

String buffer = Geeksforgeeks!
String buffer after reversing = !skeegrofskeeG

 

Program 2: 

java




// Java program to illustrate the
// java.lang.StringBuffer.reverse()
import java.lang.*;
 
public class Test {
 
    public static void main(String args[])
    {
        StringBuffer sbf = new StringBuffer("1 2 3 4 5 6 7 8 9 10");
        System.out.println("String buffer  = " + sbf);
 
        // Here it reverses the string buffer
        sbf.reverse();
        System.out.println("String buffer after reversing = " + sbf);
    }
}


Output: 

String buffer  = 1 2 3 4 5 6 7 8 9 10
String buffer after reversing = 01 9 8 7 6 5 4 3 2 1
