Java CompoundName getSuffix()用法及代碼示例

javax.naming.CompoundName類的getSuffix()方法用於獲取複合名稱對象，該複合名稱對象的組件由該複合名稱中的組件後綴組成。我們需要從此複合名稱對象開始提取後綴的位置作為參數傳遞。返回的複合名稱對象和此複合名稱對象具有相同的語法。如果我們對該複合名稱進行了任何更改，而不會影響返回的名稱，反之亦然。

用法:

public Name getSuffix(int posn)

參數：此方法接受posn，它是要從其開始的組件的從0開始的索引。必須在[0，size()]範圍內。

返回值：此方法返回由[posn，size())範圍內的索引處的組件組成的複合名稱。如果posn等於size()，則返回一個空的化合物名稱。

異常：如果posn在指定範圍之外，則此方法引發ArrayIndexOutOfBoundsException。

以下示例程序旨在說明CompoundName.getSuffix()方法：
程序1:

// Java program to demonstrate 
// CompoundName.getSuffix() 
  
import java.util.Properties; 
import javax.naming.CompoundName; 
import javax.naming.InvalidNameException; 
  
public class GFG { 
    public static void main(String[] args) 
        throws InvalidNameException 
    { 
  
        // need properties for CompoundName 
        Properties props = new Properties(); 
        props.put("jndi.syntax.separator", "@"); 
        props.put("jndi.syntax.direction", 
                  "left_to_right"); 
  
        // create compound name object 
        CompoundName CompoundName1 
            = new CompoundName( 
                "1@2@3@4@5@6@7", 
                props); 
  
        // apply getSuffix() 
        CompoundName newCompoundName 
            = (CompoundName) 
                  CompoundName1.getSuffix(3); 
  
        // print value 
        System.out.println( 
            "New CompoundName Object:"
            + newCompoundName); 
    } 
}

輸出：

New CompoundName Object:4@5@6@7

程序2:

// Java program to demonstrate 
// CompoundName.getSuffix() method 
  
import java.util.Properties; 
import javax.naming.CompoundName; 
import javax.naming.InvalidNameException; 
  
public class GFG { 
    public static void main(String[] args) 
        throws InvalidNameException 
    { 
  
        // need properties for CompoundName 
        Properties props = new Properties(); 
        props.put("jndi.syntax.separator", "/"); 
        props.put("jndi.syntax.direction", 
                  "left_to_right"); 
  
        // create compound name object 
        CompoundName CompoundName1 
            = new CompoundName( 
                "c/e/d/v/a/b/z/y/x/f", 
                props); 
  
        // apply getSuffix() 
        CompoundName newCompoundName 
            = (CompoundName) 
                  CompoundName1.getSuffix(8); 
  
        // print value 
        System.out.println( 
            "New CompoundName Object:"
            + newCompoundName); 
    } 
}

輸出：

New CompoundName Object:x/f
