Question
Reverse a string using StringBuffer.Fill the code snippet provided, to perform the above.Code : Scanner sc=new Scanner(System.in); String str=sc.next(); //Store str using StringBuffer StringBuffer sb = ; ; //reverse using sb String reverse = ; //Convert StringBuffer to String System.out.println(reverse);
Solution
Sure, here is the completed code snippet:
Scanner sc=new Scanner(System.in);
String str=sc.next();
//Store str using StringBuffer
StringBuffer sb = new StringBuffer(str);
//reverse using sb
sb.reverse();
//Convert StringBuffer to String
String reverse = sb.toString();
System.out.println(reverse);
In this code, we first read the string from the user using the Scanner class. Then, we create a StringBuffer object and initialize it with the string. We then call the reverse() method on the StringBuffer object to reverse the string. Finally, we convert the reversed string back to a String object using the toString() method and print it.
