Reverse a string in java Program using stringbuffer

Here, we are supposed to create a source code that asks for String input from the user and displays the string in reverse order.

The basic idea is to pass the Input String to StringBuffer class and then invoke the reverse() function from the class using any object declared. Here we are using ‘str’ as the object that invokes reverse( ) function. The same is displayed as a result.

Source Code:

/* Program to enter a string and print it after reversing it.*/\nimport java.io.*;\r\nclass RevStringFunc\r\n{\r\npublic static void main()throws IOException\r\n{\r\nBufferedReader bf=new BufferedReader(new InputStreamReader(System.in));\r\nSystem.out.print(\"\\n Enter String: \");\r\nString s=bf.readLine();\r\nStringBuffer str=new StringBuffer(s);\r\nstr.reverse();\r\nSystem.out.println(\"Reversed String: \"+str);
\n}\r\n}\r\n

Output:

Enter String: Tony Stark\r\nReversed String: kratS ynoT\n

Enter String: Peter Parker\r\nReversed String: rekraP reteP
