LogRecord setParameters() method in Java with Examples

The setParameters() method of java.util.logging.LogRecord is used to set the parameters to the log message.These parameters are the parameters to be inserted into the message of this LogRecord.

Syntax:

public void setParameters(Object[] parameters)

Parameters: This method accepts parameters as parameter which are the log message parameters in the form of Object[].

Return: This method returns nothing.

Below programs illustrate setParameters() method:
Program 1:

// Java program to illustrate setParameters() 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");

        // set empty object array
        logRecord.setParameters(new Object[] {});

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

Output:

Object Array length: 0

Program 2:

// Java program to illustrate setParameters() 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("800"),
            "Hi Logger");

        // get parameter object array
        // from string class method
        Method method
            = String.class.getDeclaredMethods()[4];
        System.out.println("Method : "
                           + method.getName());
        Object[] objArr
            = method.getParameters();

        // set empty object array
        logRecord.setParameters(objArr);

        // get array
        Object[] array = logRecord.getParameters();
        for (int i = 0; i < array.length; i++) {
            System.out.println(array[i]);
        }
    }
}

Output:

Method : compareTo
java.lang.Object arg0
