Java CollationElementIterator setText(String)用法及代碼示例

java.text.CollationElementIterator類的setText()方法用於將CollationElementIterator對象的新源字符串設置為要迭代。

用法:

public void setText(String source)

參數：此方法采用新的源字符串，迭代器將在該字符串上進行迭代。

返回值：此方法無返回值。

下麵是說明setText()方法的示例：

範例1：

// Java program to demonstrate 
// setText() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing testString 
        String test = "GeeksForGeeks"; 
  
        // creating and initializing 
        // RuleBasedCollator object 
        RuleBasedCollator rbc 
            = (RuleBasedCollator)(Collator.getInstance()); 
  
        // creating and initializing 
        // CollationElementIterator 
        CollationElementIterator cel 
            = rbc.getCollationElementIterator(test); 
  
        String str = "Code"; 
  
        // setting new text using 
        // setText() method 
        cel.setText(str); 
  
        // for iteration 
        for (int i = 1; i <= str.length(); i++) { 
  
            // getting primary component of every elmenet 
            // using primaryOrder() method 
            int value 
                = CollationElementIterator 
                      .primaryOrder(cel.next()); 
  
            // display the reslut 
            System.out.println("primary order "
                               + "for order "
                               + i + " is "
                               + value); 
        } 
    } 
}

輸出：

primary order for order 1 is 84
primary order for order 2 is 97
primary order for order 3 is 85
primary order for order 4 is 87

範例2：

// Java program to demonstrate 
// setText() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        // creating and initializing testString 
        String test = "GeeksForGeeks"; 
  
        // creating and initializing 
        // RuleBasedCollator object 
        RuleBasedCollator rbc 
            = (RuleBasedCollator)(Collator.getInstance()); 
  
        // creating and initializing 
        // CollationElementIterator 
        CollationElementIterator cel 
            = rbc.getCollationElementIterator(test); 
  
        String str = "Tajmahal"; 
  
        // setting new text using 
        // setText() method 
        cel.setText(str); 
  
        // for iteration 
        for (int i = 1; i <= str.length(); i++) { 
  
            // getting primary component of every elmenet 
            // using primaryOrder() method 
            int value 
                = CollationElementIterator 
                      .primaryOrder(cel.next()); 
  
            // display the reslut 
            System.out.println("primary order "
                               + "for order "
                               + i + " is "
                               + value); 
        } 
    } 
}

輸出：

primary order for order 1 is 102
primary order for order 2 is 82
primary order for order 3 is 92
primary order for order 4 is 95
primary order for order 5 is 82
primary order for order 6 is 90
primary order for order 7 is 82
primary order for order 8 is 94
