Below programs illustrate the java.lang.StringBuffer.reverse() method:
Program 1:






// Java praogram 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 praogram 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
