Return Type: It returns true if the stated predicate holds true for some elements of the list else it returns false.

Example #1:

// Scala program of exists()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a list
        val m1 = List(1, 2, 3, 4, 5)

        // Applying exists method
        val result = m1.exists(y => {y % 3 == 0})

        // Displays output
        println(result)

    }
}

Output:

true

Example #2:

// Scala program of exists()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a list
        val m1 = List(1, 2, 3, 4, 5)

        // Applying exists method
        val result = m1.exists(y => {y % 9 == 0})

        // Displays output
        println(result)

    }
}

Output:
