The equals() method of java.text.Collator class is used to check if both the Collator objects are same or not.
Syntax:
public boolean equals(Object that)
Parameter: This method takes two Collator objects between which comparison is going to take place.
Return Value: if both Collator objects are equal to each other then it will return true otherwise false.
Below are the examples to illustrate the equals() method:
Example 1:
Java
// Java program to demonstrate // equals() 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_1 = new RuleBasedCollator(simple); // Creating and initializing // Collator Object Collator col_2 = Collator.getInstance(Locale.US); // compare both object // using equals() method boolean i = col_1.equals(col_2); // display result if (i) System.out.println(col_1 + " is equal to " + col_2); else System.out.println(col_1 + " is not equal to " + col_2); } catch (ClassCastException e) { System.out.println( "Exception thrown : " + e); } catch (ParseException e) { System.out.println( "Exception thrown : " + e); } } } |
java.text.RuleBasedCollator@5eb2e1c2 is not equal to java.text.RuleBasedCollator@289747d6
Example 2:
Java
// Java program to demonstrate // equals() 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_1 = Collator.getInstance(Locale.UK); // Creating and initializing // Collator Object Collator col_2 = Collator.getInstance(Locale.US); // compare both object // using equals() method boolean i = col_1.equals(col_2); // display result if (i) System.out.println(col_1 + " is equal to " + col_2); else System.out.println(col_1 + " is not equal to " + col_2); } catch (ClassCastException e) { System.out.println( "Exception thrown : " + e); } } } |
java.text.RuleBasedCollator@289747d6 is equal to java.text.RuleBasedCollator@289747d6
