Java中的级别 equals() 方法和示例

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

句法：

public boolean equals(Object ox)

参数：此方法接受一个对象 ox，它是要与之比较的参考对象。

Return ：当且仅当两个对象具有相同的级别值时，此方法才返回 true。

下面的程序说明了 equals() 方法：
方案一：

// 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

方案二：

// 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
