Scala String compareToIgnoreCase()用法及代碼示例


compareToIgnoreCase()方法用於比較兩個字符串,例如compareTo方法,但是在比較時忽略大小寫(大寫或小寫)差異。

函數定義:int compareToIgnoreCase(String str)
返回類型: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) 
      
    } 
} 
輸出:
0

範例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) 
      
    } 
} 
輸出:
0

在此,即使大小寫不同,兩個字符串也被視為相同。
範例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) 
      
    } 
} 
輸出:
1
