Hello hello, everyone, today in this video I will show you guys how to check if an array contains any duplicate. If you are wondering what is duplicate in array means then don't worry, it just the repeated elements. For example, a repeated number in an array of integers or a repeated string in an array of strings.
The basic solution for this problem is using a nested loop. The outer loop will select an element and the inner loop will compare with the selected element. If they are matched, store the duplicated character in another array so we can print it out later.
This is also a good Java programming exercise for beginners to practice coding.
I have also posted a GitHub link to the code.
