Collator getStrength() method in Java with Example

The getStrength() method of java.text.Collator class is used to get the strength property of Collator object which will help that object during comparison.

Syntax:

public int getStrength()

Parameter: This method does not accept any parameter.
Return Value: This method returns the strength property of the Collator object which will help that object during comparison.

Below are the examples to illustrate the getStrength() method:

Example 1:

Java

// Java program to demonstrate
// getStrength() 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);

            // setting strength property
            // for the Collator object
            col.setStrength(Collator.IDENTICAL);

            // getting strength property
            // using getStrength() method
            int strength = col.getStrength();

            // display result
            if (strength == 0)
                System.out.println(
                    "current strength "
                    + "property :- PRIMARY.");
            else if (strength == 1)
                System.out.println(
                    "current strength "
                    + "property :- SECONDARY.");
            else if (strength == 2)
                System.out.println(
                    "current strength"
                    + " property :-  TERTIARY.");
            else
                System.out.println(
                    "current strength "
                    + "property :- IDENTICAL.");
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : " + e);
        }
        catch (ParseException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

current strength property :- IDENTICAL.

Example 2:

Java

// Java program to demonstrate
// getStrength() 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 strength property
            // using getStrength() method
            int strength = col.getStrength();

            // display result
            if (strength == 0)
                System.out.println(
                    "current strength "
                    + "property :- PRIMARY.");
            else if (strength == 1)
                System.out.println(
                    "current strength "
                    + "property :- SECONDARY.");
            else if (strength == 2)
                System.out.println(
                    "current strength "
                    + "property :-  TERTIARY.");
            else
                System.out.println(
                    "current strength "
                    + "property :- IDENTICAL.");
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

current strength property :-  TERTIARY.
