Java Level equals()用法及代码示例

java.util.logging.Level的equals()方法用于检查此级别的对象是否等于传递的对象。如果两个对象相等，则方法将返回true，否则返回false。

用法:

public boolean equals(Object ox)

参数：此方法接受对象ox，它是要与之进行比较的参考对象。

返回：仅当两个对象具有相同的级别值时，此方法返回true。

以下示例程序旨在说明equals()方法：
示例1:

// Java program to illustrate equals() method 
  
import java.util.logging.Level; 
import java.util.logging.Logger; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Create a Logger 
        Logger logger 
            = Logger.getLogger( 
                        Object.class.getName()) 
                  .getParent(); 
  
        // Get level of logger 
        Level level1 
            = logger.getLevel(); 
  
        // Create a second Logger 
        Logger logger2 
            = Logger.getLogger( 
                        String.class.getName()) 
                  .getParent(); 
  
        // Get level of second logger 
        Level level2 
            = logger2.getLevel(); 
  
        // apply equal method 
        boolean value = level1.equals(level2); 
  
        // print level names 
        System.out.println("Both level are equal = "
                           + value); 
    } 
}

输出：

Both level are equal = true

示例2:

// Java program to illustrate equals() method 
  
import java.util.ArrayList; 
import java.util.logging.Level; 
import java.util.logging.Logger; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Create a Logger 
        Logger logger 
            = Logger.getLogger( 
                        Object.class.getName()) 
                  .getParent(); 
  
        // Get level of logger 
        Level level1 
            = logger.getLevel(); 
  
        // Create a second Logger for ArrayList class 
        Logger logger2 
            = Logger.getLogger( 
                ArrayList.class.getName()); 
  
        // Get level of second logger 
        Level level2 
            = logger2.getLevel(); 
  
        // apply equal method 
        boolean value = level1.equals(level2); 
  
        // print level names 
        System.out.println("Both level are equal = "
                           + value); 
    } 
}

输出：

Both level are equal = false
