Java CompoundName hashCode()用法及代码示例

javax.naming.CompoundName类的hashCode()方法用于返回此化合物名称的哈希码。该复合名称对象的哈希码是该复合名称各个组成部分的“canonicalized”形式的哈希码的总和。

用法:

public int hashCode()

参数：此方法不接受任何内容。

返回值：此方法返回一个表示此名称的哈希码的int。

以下示例程序旨在说明CompoundName.hashCode()方法：
程序1:

// Java program to demonstrate 
// CompoundName.hashCode() 
  
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( 
                "a:b:z:y:x", props); 
  
        // apply hashCode() 
        int hashCode 
            = CompoundName1.hashCode(); 
  
        // print value 
        System.out.println("hashCode:"
                           + hashCode); 
    } 
}

输出：

hashCode:558

程序2:

// Java program to demonstrate 
// CompoundName.hashCode() 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 hashCode() 
        int hashCode 
            = CompoundName1.hashCode(); 
  
        // print value 
        System.out.println("hashCode:"
                           + hashCode); 
    } 
}

输出：

hashCode:1078
