带有示例的 Scala String compareToIgnoreCase() 方法

compareToIgnoreCase()方法用于比较两个字符串，如compareTo方法，但在比较时忽略大小写（大写或小写）差异。

Method Definition:int compareToIgnoreCase(String str)
Return Type:It is same as compareTo() method but here only case difference is ignored.

示例：1#

// Scala program of compareToIgnoreCase()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
        // Creating a String
        val m1 = "Nidhi"
          
        // Applying compareToIgnoreCase() method
        val result = m1.compareToIgnoreCase("Nidhi")
          
        // Displays output
        println(result)
      
    }
} 

输出：

0

示例 #2：

// Scala program of compareToIgnoreCase()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
        // Creating a String
        val m1 = "Nidhi"
          
        // Applying compareToIgnoreCase() method
        val result = m1.compareToIgnoreCase("NiDhi")
          
        // Displays output
        println(result)
      
    }
} 

输出：

0

在这里，即使存在大小写差异，两个字符串也被认为是相同的。
示例#3：

// Scala program of compareToIgnoreCase()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
        // Creating a String
        val m1 = "Nidhi"
      
        // Applying compareToIgnoreCase() method
        val result = m1.compareToIgnoreCase("NiDh")
      
        // Displays output
        println(result)
      
    }
} 

输出：

1
