The max() method is utilized to return the largest method of the TreeSet.

Method Definition: def max: A

Return Type: It returns the largest element of the TreeSet.

Example #1:

 `// Scala program of max() ``// method `` ` `// Import TreeSet``import` `scala.collection.mutable.``_`` ` `// Creating object ``object` `GfG ``{ `` ` `    ``// Main method ``    ``def` `main(args``:``Array[String]) ``    ``{ ``     ` `        ``// Creating TreeSet``        ``val` `q``1` `=` `TreeSet(``1``, ``2``, ``3``, ``4``, ``5``)  ``           ` `        ``// Print the TreeSet ``        ``println(q``1``) ``         ` `        ``// Applying max method  ``        ``val` `result ``=` `q``1``.max  ``           ` `        ``// Displays output  ``        ``print(``"Largest element in the TreeSet: "` `+ result) ``         ` `    ``} ``} `
Output:
```TreeSet(1, 2, 3, 4, 5)
Largest element in the TreeSet: 5
```

Example #2:

 `// Scala program of max() ``// method `` ` `// Import TreeSet``import` `scala.collection.mutable.``_`` ` `// Creating object ``object` `GfG ``{ `` ` `    ``// Main method ``    ``def` `main(args``:``Array[String]) ``    ``{ ``     ` `        ``// Creating TreeSet``        ``val` `q``1` `=` `TreeSet(``"u"``, ``"a"``, ``"i"``, ``"o"``, ``"e"``)  ``           ` `        ``// Print the TreeSet ``        ``println(q``1``) ``         ` `        ``// Applying max method  ``        ``val` `result ``=` `q``1``.max  ``           ` `        ``// Displays output  ``        ``print(``"Largest element in the TreeSet: "` `+ result) ``         ` `    ``} ``} `
Output:
```TreeSet(a, e, i, o, u)
