Answer 1

Explanation:

❤️ Heya mate6

Here is your answer

☆ ❣ This java program reads a string from the user, and prints out only the unique characters in the string in insertion order.

☆ First we find out the frequency of each character in the string and then print out only the characters that have frequency as 1. To maintain the insertion order, we use LinkedHashMap class from collections framework.
