Java Collator setDecomposition()用法及代码示例

java.text.Collator类的setdecomposition()方法用于设置此整理器的分解模式。

用法:

public void setDecomposition(int decompositionMode)

参数：此方法将整数值作为参数，代表此整理器的等效分解模式。

返回值：此方法无返回值。

下面是说明setDecomposition()方法的示例：

范例1：

// Java program to demonstrate 
// setDecomposition() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initalizing new simple rule 
            String simple = "< a < b < c < d"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // setting decomposition mode 
            // into the Collator object 
            // using setDecomposition() mehtod 
            col.setDecomposition( 
                Collator.CANONICAL_DECOMPOSITION); 
  
            // getting decompostiton mode 
            int mode = col.getDecomposition(); 
  
            // display result 
            if (mode == 0) 
                System.out.println( 
                    "decompostiton mode"
                    + " is:- NO_DECOMPOSITION"); 
            else if (mode == 1) 
                System.out.println( 
                    "decompostiton mode is"
                    + ":- CANONICAL_DECOMPOSITION"); 
            else
                System.out.println( 
                    "decompostiton mode is "
                    + ":- FULL_DECOMPOSITION. "); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

decompostiton mode is:- CANONICAL_DECOMPOSITION

范例2：

// Java program to demonstrate 
// setDecomposition() 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 decomposition mode 
            // into the Collator object 
            // using setDecomposition() mehtod 
            col.setDecomposition(Collator.FULL_DECOMPOSITION); 
  
            // getting decompostiton mode 
            int mode = col.getDecomposition(); 
  
            // display result 
            if (mode == 0) 
                System.out.println( 
                    "decompostiton mode"
                    + " is:- NO_DECOMPOSITION"); 
            else if (mode == 1) 
                System.out.println( 
                    "decompostiton mode is"
                    + ":- CANONICAL_DECOMPOSITION"); 
            else
                System.out.println( 
                    "decompostiton mode is "
                    + ":- FULL_DECOMPOSITION. "); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

decompostiton mode is:- FULL_DECOMPOSITION.
