Java CompoundName equals()用法及代码示例

javax.naming.CompoundName类的equals()方法用于比较此CompoundName与作为参数传递的指定对象，并检查两个对象是否相等。如果两个对象相等，则equals()方法返回true，否则返回false。如果传递的obj为null或不是复合名称，则该方法返回false。如果一个组件中的每个组件与另一个组件中的相应组件相等，则两个复合对象相等。

用法:

public boolean equals(Object obj)

参数：此方法接受obj，它是要与之比较的非null对象。

返回值：如果obj等于此复合名称，则此方法返回true，否则返回false。

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

// Java program to demonstrate 
// CompoundName.equals() 
  
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( 
                "x:y:z", props); 
        CompoundName CompoundName2 
            = new CompoundName( 
                "x:y:m", props); 
  
        // apply equals() 
        boolean flag 
            = CompoundName1 
                  .equals(CompoundName2); 
  
        // print value 
        if (flag) 
            System.out.println( 
                "CompoundName1 is "
                + "equal to CompoundName2"); 
        else
            System.out.println( 
                "CompoundName1 is "
                + "not equal to CompoundName2"); 
    } 
}

输出：

CompoundName1 is not equal to CompoundName2

程序2:

// Java program to demonstrate 
// CompoundName.equals() 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( 
                "x@y@z@M@n", props); 
        CompoundName CompoundName2 
            = new CompoundName( 
                "x@y@z@M@n", props); 
  
        // apply equals() 
        boolean flag 
            = CompoundName1.equals(CompoundName2); 
  
        // print value 
        if (flag) 
            System.out.println( 
                "CompoundName1 is "
                + "equal to CompoundName2"); 
        else
            System.out.println( 
                "CompoundName1 is "
                + "not equal to CompoundName2"); 
    } 
}

输出：

CompoundName1 is equal to CompoundName2
