The filter() method is utilized to select all elements of the map which satisfies a stated predicate.

Method Definition: def filter(p: ((A, B))=> Boolean): Map[A, B]

Return Type: It returns a new map consisting all the elements of the map which satisfies the given predicate.

Example #1:




// Scala program of filter()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating map
        val m1 = Map("geeks" -> 5, "for" -> 3)
          
        // Applying filter method
        val result = m1.filter(x => x._1 == "geeks" && x._2 == 5)
          
        // Displays output
        println(result)
      
    }
}

Output:

Map(geeks -> 5)

Example #2:




// Scala program of filter()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating map
        val m1 = Map("geeks" -> 5, "for" -> 3)
          
        // Applying filter method
        val result = m1.filter(x => x._1 == "for" && x._2 == 5)
          
        // Displays output
        println(result)
      
    }
}

Output:

Map()

Here, an empty map is returned as none of the elements satisfy the stated predicate.
