LogRecord setSourceClassName() method in Java with Examples

The setSourceClassName() method of java.util.logging.LogRecord is used to set the name of the class that allegedly issued the logging request. The source class name which is used in logRecord for logging purpose has to be set via this method.

Syntax:

public void setSourceClassName(String sourceClassName)

Parameters: This method accepts sourceClassName as parameter which is the source class name. It can be null also.

Return: This method returns nothing.

Below programs illustrate setSourceClassName() method:
Program 1:

// Java program to illustrate
// setSourceClassName() 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.SEVERE,
                            "Hello Logger");

        // set String class as source class
        logRecord.setSourceClassName(
            String.class.getName());

        // print the class name
        System.out.println(
            "Source class Name = "
            + logRecord.getSourceClassName());
    }
}

Output:

Source class Name = java.lang.String

Program 2:

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

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

public class GFG {

    public static void main(String[] args)
    {

        // Create LogRecord object
        LogRecord logRecord
            = new LogRecord(Level.INFO,
                            "GFG Logger");

        // set ArrayList class as source class
        logRecord.setSourceClassName(
            ArrayList
                .class
                .getName());

        // print the class name
        System.out.println(
            "Source class Name = "
            + logRecord.getSourceClassName());

        // now set null as class name
        logRecord.setSourceClassName(null);

        // print the class name
        System.out.println(
            "Now new Source class Name = "
            + logRecord.getSourceClassName());
    }
}

Output:

Source class Name = java.util.ArrayList
Now new Source class Name = null
