LogRecord getParameters() method in Java with Examples

Last Updated : 23 Oct, 2019

The getParameters() method of java.lang.reflect.LogRecord is used to get the parameters to the log message.These parameters are the parameters to be inserted into the message of this LogRecord. Syntax:

public Object[] getParameters()

Parameters: This method accepts nothing. Return: This method returns the log message parameters.It can be null if there are no parameters to return. Below programs illustrate getParameters() method: Program 1:

Java

// Java program to illustrate
// getParameters() method

import java.util.logging.Level;
import java.util.logging.LogRecord;

public class GFG {

    public static void main(String[] args)
    {

        // Create LogRecord object
        LogRecord logRecord = new LogRecord(
            Level.parse("800"),
            "Hi Logger");

        logRecord.setParameters(
            new Object[] {});

        // get object parameters
        Object[] params
            = logRecord.getParameters();

        System.out.println(
            "Object Array length: "
            + params.length);
    }
}

Output:

Object Array length: 0

Program 2:

Java

// Java program to illustrate
// getParameters() method

import java.lang.reflect.Method;
import java.util.logging.Level;
import java.util.logging.LogRecord;

public class GFG {

    public static void main(String[] args)
    {

        // Create LogRecord object
        LogRecord logRecord = new LogRecord(
            Level.parse("400"),
            "GFG logger");

        Object[] objArr
            = String
                  .class
                  .getDeclaredMethods()[4]
                  .getParameters();
        logRecord.setParameters(objArr);

        // get object parameters
        Object[] params
            = logRecord.getParameters();

        for (int i = 0; i < params.length; i++) {
            System.out.println(params[i]);
        }
    }
}
