Help with looping logic
1. I am new to this forum, can someone let me know how I attach a code tag.
2. Im doing an exercise where I have to enter 20 values into an array . Each value I enter has to be different from a value previously entered value.If the value already exists in the array, the program should allow the user to put in a another value. I have been trying nested for loops but im just confused. Can someone help me on how to go about it ?

for (loop twenty times)
ask user for value
while (value is in the array) ask user for new value
insert value into array
next
to place code use [ code ] and [ /code ] minuse the spaces...
you can use a nested loop I guess if you just make it have an if statement that checks if the ArrayList contains the object. if it does have it go into a loop that aska for a different input and breaks only if the ArrayList doesn't contain the new input.
