Following are the explanation of the java program
- Create an instance of scanner class i.e "scr1".
- Print the message on screen What is your name? by using System.out.println() method.
- iterating the do-while loop for input in the "str" variable. If the user enters nothing then again asked for the input.
- if(str.length() > 0) condition is used to terminate the loop if user input the string.
- Finally, print the string in proper format which is mention in the question.
