Java CompoundName getSuffix()用法及代码示例

javax.naming.CompoundName类的getSuffix()方法用于获取复合名称对象，该复合名称对象的组件由该复合名称中的组件后缀组成。我们需要从此复合名称对象开始提取后缀的位置作为参数传递。返回的复合名称对象和此复合名称对象具有相同的语法。如果我们对该复合名称进行了任何更改，而不会影响返回的名称，反之亦然。

用法:

public Name getSuffix(int posn)

参数：此方法接受posn，它是要从其开始的组件的从0开始的索引。必须在[0，size()]范围内。

返回值：此方法返回由[posn，size())范围内的索引处的组件组成的复合名称。如果posn等于size()，则返回一个空的化合物名称。

异常：如果posn在指定范围之外，则此方法引发ArrayIndexOutOfBoundsException。

以下示例程序旨在说明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); 
    } 
}

输出：

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); 
    } 
}

输出：

New CompoundName Object:x/f
