How to filter equal strings and get just one of each

I have a list of items that contains groups, when I print them, it shows all items.

I tried this way:

let item = playlist?.objects.map({ $0.group != group })
-> Unable to infer closure type in the current context

And this way:

    for group in item! {
if group.self != group {
alertController.addAction(UIAlertAction(title: String(group), style: .default) {
action in
})
print(group)
}
}

@IBAction func button(_ sender: Any) {

    let alertController = UIAlertController(title: "", message: "", preferredStyle: .alert)

    let item = playlist?.objects.map({ $0.group != group })

    for group in item! {
        if group.self == group {
            alertController.addAction(UIAlertAction(title: String(group), style: .default) {
                action in
            })
            print(group)
        }
    }

    alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel))

    self.present(alertController, animated: true, completion: nil)
}

What I want to archive is to remove duplicate groups.

After mapping the group names, put that array into a set to get the unique group names.

let uniqueGroups = Set(playlist?.objects.map({ $0.group != group }) ?? [])

Java String Equals Example | String equals() In Java

In Java, objects of strings are immutable, so that means we cannot once the string is created. Now, if we have two strings and we want to compare them if they are the same or not, then we can use the equals()method.

Java String Equals Example

Java String equals() method compares the two given strings based on the content of a string.

If any character is not matched, then it returns false and if all characters are matched, it returns true.

  1. Java String equals() method overrides an Object class equals() method implementation.
  2. Java String is immutable, checking the equality of string to another object should be done using equals() method rather than == operator.
  3. String equals() method always returns a boolean value; it doesn’t throw any exceptions.
  4. The result of the equals() method is true if and only if an argument is not null, it’s the String object, represents the same sequence of characters as this string.

See the following syntax.

string1.equals(string2);

#java #java string equals #equals

Python String Equals Example | Python String Comparison

Python String comparison can be performed using equal (==) and comparison (<, >, !=, <=, >=) operators. There are no particular functions to compare two strings in Python. Strings in python are contiguous series of characters delimited by single or double-quotes. Python doesn’t have any separate data type for characters, so they are represented as a single character string.

Python String Equals

The equal operator is used to compare two strings. It compares one by one character of both strings. When different characters are found in string, then their Unicode value is compared. In Python, the character with lower Unicode value is considered to be smaller and higher unicode value considered to be higher.

#python #equals #python string equals
