下麵是說明getCollationKey()方法的示例:

範例1:

// Java program to demonstrate 
// getCollationKey() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new simple rule 
            String simple 
                = "< a < b < c < d"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // getting sereis of bits 
            // using getCollationKey() mehtod 
            CollationKey key 
                = col.getCollationKey("Geek"); 
  
            // display result 
            System.out.println( 
                "Series of bits are:- "
                + key.getSourceString()); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}
輸出:
Series of bits are:- Geek

範例2:

// Java program to demonstrate 
// getCollationKey() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing 
            // new simple rule 
            String simple 
                = "< a < b < c < d"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // getting sereis of bits 
            // using getCollationKey() mehtod 
            CollationKey key 
                = col.getCollationKey("G_f_G"); 
  
            // display result 
            System.out.println( 
                "Series of bits are:- "
                + key.getSourceString()); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}
輸出:
Series of bits are:- G_f_G
