getuseParentAndlers()一个记录器类的方法，用于获取布尔值，该值回答该记录器是否将其输出发送给其父记录器。

语法:

public boolean getUseParentHandlers()

参数:此方法不接受任何内容。

返回值:如果输出要发送到记录器的父级，该方法返回真。

下面的程序说明了 getUseParentHandlers()方法:

程序 1:

// Java program to demonstrate
// Logger.getUseParentHandlers() method

import java.util.logging.Logger;

public class GFG {

    private static Logger logger
        = Logger.getLogger(
            GFG.class
                .getPackage()
                .getName());

    public static void main(String args[])
    {

        // Check output is to be
        // sent to the logger's parent
        boolean flag
            = logger.getUseParentHandlers();

        // Log the flag value
        logger.info("output sent to the"
                    + " logger's parent - "
                    + flag);
    }
}

在 eclipse IDE 上打印的输出如下所示-

程序 2:

// Java program to demonstrate
// Logger.getUseParentHandlers() method

import java.util.logging.Logger;

public class GFG {

    private static Logger logger
        = Logger.getLogger(
            GFG.class
                .getPackage()
                .getName());

    public static void main(String args[])
    {

        // Set setUseParentHandlers
        logger.setUseParentHandlers(false);

        // Check output is to be
        // sent to the logger's parent
        boolean flag = logger.getUseParentHandlers();

        // Print value
        System.out.println("output sent to the"
                           + " logger's parent - "
                           + flag);
    }
}
