Método Collator setStrength() en Java con ejemplo

El método setStrength() de la clase java.text.Collator se usa para establecer la propiedad de fuerza del objeto Collator que ayudará a ese objeto durante la comparación de dos strings.
Sintaxis: 
 

public void setStrength(int newStrength)

Parámetro : este método acepta la propiedad de fuerza del objeto Collator como parámetro que ayudará a este objeto durante la comparación.
Valor devuelto: este método no tiene nada que devolver.
A continuación se muestran los ejemplos para ilustrar el método setStrength() :
Ejemplo 1: 
 

// Java program to demonstrate
// setStrength() 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
            // using getStrength() method
            col.setStrength(Collator.IDENTICAL);
 
            // getting strength property
            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);
        }
    }
}

current strength property :- IDENTICAL.

Ejemplo 2: 
 

// Java program to demonstrate
// setStrength() 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);
 
            // setting strength property
            // for the Collator object
            // using getStrength() method
            col.setStrength(Collator.PRIMARY);
 
            // getting strength property
            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);
        }
    }
}

current strength property :- PRIMARY.
