// String Reverse in Java using StringBuilder's Built-in Method reverse()

    	Scanner in = new Scanner(System.in);
        System.out.println("Enter a string to make reverse::\n");
        String x=in.nextLine();
        
        // It will create the instance of the `StringBuilder` class
        StringBuilder SBinput=new StringBuilder();
        SBinput.append(x); // To append the value of x variable
        
        // It will reverse the input value
        SBinput.reverse();
        
        //  It will print the final output
        System.out.println("The reverse of the string is:: "+SBinput+"\n");
