javax.naming.CompositeName類的get()方法用於獲取此複合名稱對象的組件。位置作為參數傳遞,用於從複合名稱對象獲取該位置上存在的組件。
用法:
public String get(int posn)
參數:此方法接受posn,它是要檢索的組件的從0開始的索引。必須在[0,size())範圍內。
返回值:此方法返回索引posn處的組件。
異常:如果posn在指定範圍之外,則此方法引發ArrayIndexOutOfBoundsException。
下麵的程序說明CompositeName.get()方法:
程序1:
// Java program to demonstrate
// CompositeName.get()
import java.util.Properties;
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args) throws InvalidNameException
{
// create composite name object
CompositeName CompositeName1
= new CompositeName(
"a/baz/ay/x");
// apply get()
String comp1 = CompositeName1.get(0);
String comp2 = CompositeName1.get(3);
// print value
System.out.println(comp1);
System.out.println(comp2);
}
}
輸出:
a x
程序2:
// Java program to demonstrate
// CompositeName.get() method
import java.util.Properties;
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
// create composite name object
CompositeName CompositeName1
= new CompositeName(
"c/e/d/v/a/b/z/y/x/f");
// apply get()
String pos3 = CompositeName1.get(3);
String pos4 = CompositeName1.get(4);
// print value
System.out.println(
"Component at position 3:"
+ pos3);
System.out.println(
"Component at position 4:"
+ pos4);
}
}
輸出:
Component at position 3:v Component at position 4:a
