The getCollationKey() method of java.text.Collator class is used to get the series of bit converted from string passed into it.
Syntax:
public abstract CollationKey
getCollationKey(String source)
Parameter: This method accepts the string object as a parameter.
Return Value: This method returns the series of bit converted from the string passed into it.
Below are the examples to illustrate the getCollationKey() method:
Example 1:
Java
// Java program to demonstrate// getCollationKey() methodimport 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 series of bits // using getCollationKey() method 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); } }} |
Output:
Series of bits are :- Geek
Example 2:
Java
// Java program to demonstrate// getCollationKey() methodimport 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 series of bits // using getCollationKey() method CollationKey key = col.getCollationKey("CodeBlock"); // display result System.out.println( "Series of bits are :- " + key.getSourceString()); } catch (ClassCastException e) { System.out.println("Exception thrown : " + e); } }} |
Output:
Series of bits are :- CodeBlock
