Java 中的 CompoundName getSuffix()方法,带示例
原文:https://www . geesforgeks . org/compound name-get suffix-method-in-Java-with-examples/
一个 javax.naming.CompoundName 类的 getSuffix() 方法用于获取一个复合名称对象,该复合名称对象的组件由该复合名称中组件的后缀组成。我们需要从这个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共享相同的语法。如果我们对这个复合名称进行任何更改,都不会影响返回的名称,反之亦然。
语法:
public Name getSuffix(int posn)
参数:该方法接受 posn,posn 是从 0 开始的组件索引。必须在[0,size()]范围内。
返回值:该方法返回一个复合名称,该名称由[posn,size()]范围内索引处的组件组成。如果 posn 等于 size(),则返回一个空的复合名称。
异常:如果 posn 在指定范围之外,此方法将引发 ArrayIndexOutOfBoundsException。
下面的程序说明了 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);
}
}
Output:
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);
}
}
Output:
New CompoundName Object: x/f
