Java Collator hashCode()用法及代碼示例

java.text.Collator類的hashCode()方法用於獲取此Collator對象的hashCode。

用法:

public abstract int hashCode()

參數：此方法不接受任何參數。

返回值：此方法以整數格式返回哈希碼值。

下麵是說明hashCode()方法的示例：

範例1：

// Java program to demonstrate 
// hashCode() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initalizing new simple rule 
            String simple = "< a < b < c < d"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // getting hashCode of this object 
            // using hashCode() mehtod 
            int hash = col.hashCode(); 
  
            // display result 
            System.out.println("hashCode is:- "
                               + hash); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:"
                               + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:"
                               + e); 
        } 
    } 
}

輸出：

hashCode is:- 1882448026

範例2：

// Java program to demonstrate 
// hashCode() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing Collator Object 
            Collator col 
                = Collator.getInstance(Locale.UK); 
  
            // getting hashCode of this object 
            // using hashCode() mehtod 
            int hash = col.hashCode(); 
  
            // display result 
            System.out.println("hashCode is:- " + hash); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

輸出：

hashCode is:- 681002966
