Java Collator setStrength()用法及代码示例

java.text.Collator类的setStrength()方法用于设置Collator对象的强度属性，该属性将在比较两个字符串时帮助该对象。

用法:

public void setStrength(int newStrength)

参数：此方法接受Collator对象的强度属性作为参数，这将在比较期间帮助此对象。

返回值：此方法无返回值。

下面是说明setStrength()方法的示例：

范例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() mehtod 
            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); 
        } 
    } 
}

输出：

current strength property:- IDENTICAL.

范例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() mehtod 
            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); 
        } 
    } 
}

输出：

current strength property:- PRIMARY.
