Question

"After the first calculation is performed, the program should ask the user if they would like to continue. They will type in the word “quit” if they wish to end the program. If they wish to continue, they will enter yes than enter a new length of a triangle side and the string they would like on their sign."

How could I show this in code? Please give examples asap. I don't understand loops at all. In java please

}
/***************output***************/

Enter triangle side: 343
Enter Sign: dfhd
You have entered side = 343 and sign = dfhd
Do you want to continue:(Y/N):
yes
Enter triangle side: 5454
Enter Sign: dfdfd
You have entered side = 5454 and sign = dfdfd
Do you want to continue:(Y/N):
n

Please let me know if you have any doubt or modify the answer, Thanks :)
