Scala TreeSet equals() 方法与示例
在 Scala TreeSet class
中, equals()方法用于检查两个 TreeSet 是否包含完全相同的元素。
Method Definition: def equals(o: Any): Boolean
Return Type: It returns true if both the TreeSets are equal or else returns false.
示例 #1:
// Scala program of equals()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(1, 3, 2, 7, 6, 5)
val t2 = TreeSet(1, 3, 2, 7, 6, 5)
// Print the TreeSets
println("t1: " + t1)
println("t2: " + t2)
// Applying equals() method
val result = t1.equals(t2)
// Displays output
println("Both the TreeSets are equal: " + result)
}
}
输出:
t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(1, 2, 3, 5, 6, 7)
Both the TreeSets are equal: true
示例 #2:
// Scala program of equals()
// method
// Import TreeSet
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSets
val t1 = TreeSet(1, 3, 2, 7, 6, 5)
val t2 = TreeSet(3, 2, 7, 6, 5)
// Print the TreeSets
println("t1: " + t1)
println("t2: " + t2)
// Applying equals() method
val result = t1.equals(t2)
// Displays output
println("Both the TreeSets are equal: " + result)
}
}
输出:
t1: TreeSet(1, 2, 3, 5, 6, 7)
t2: TreeSet(2, 3, 5, 6, 7)
Both the TreeSets are equal: false
