Scala Char compareTo()用法及代码示例

compareTo()方法用于将指定的字符值与参数列表中的值进行比较。与比较方法相同。

函数定义: def compareTo(arg0: Character): Int

返回类型: It returns Int. Where, if the stated character value is greater than ‘x’ then a positive integer is returned, if its less than ‘x’ then a negative integer is returned and if its equal to ‘x’ then zero is returned.

示例：1＃

// Scala program of compareTo() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Applying compareTo() method  
        val result = 'a'.compareTo('A') 
          
        // Displays output 
        println(result) 
      
    } 
}

输出：
