StringClass $-$ Put all the code in the main method

The program will prompt for a string using the text: "Enter input: $".$ It will read the input using the next method $($assume input is just one word$).$ If the length of the input is $3$ or less, it will just print the input Thack out. If the length of the input is between $4$ to $6($inclusive of both bounds$),$ it will print out the input concatenated to itself. If the length of the input is larger than $6,$ it will print out the input concatenated to itself $3$ times.
