Scala Int compareTo() 方法与示例

compareTo()方法用于在第一个整数值等于第二个整数值时返回 0，如果第一个整数值大于第二个整数值则返回 1，最后如果第一个整数值小于第二个整数值则返回 -1。

Method Definition: (First_Integer_Value).compareTo(Second_Integer_Value) 
Return Type: It returns 0 if the first integer value is equal to the second integer value, 1 if the first one is greater then the second one and finally -1 if the first one is less than the second one.

示例 #1：

Scala

// Scala program of Int compareTo()
// method
 
// Creating object
object GfG
{
 
    // Main method
    def main(args:Array[String])
    {
     
        // Creating first Int number
        val m1 = 3
         
        // Applying compareTo method
        val result = m1.compareTo(3)
         
        // Displays output
        println(result)
     
    }
}

输出：

0

object GfG
{
 
    // Main method
    def main(args:Array[String])
    {
     
        // Creating first Int number
        val m1 = 3
         
        // Applying compareTo method
        val result = m1.compareTo(2)
         
        // Displays output
        println(result)
     
    }
}

输出：

1

    // Main method
    def main(args:Array[String])
    {

        // Displays output
        println(result)
     
    }
}

输出：
