The setThrown() method of java.util.logging.LogRecord is used to a throwable associated with the log event.This is used to log Exceptions in the logRecord that can be used for logging messages. Syntax:

public void setThrown(Throwable thrown)

Parameters: This method accepts thrown as a parameter which is a throwable object. It can be null also. Return: This method returns nothing. Below programs illustrate setThrown() method: Program 1:

Java

// Java program to illustrate setThrown() method

import java.io.IOException;
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 throwable object
        logRecord.setThrown(
            new IOException(
                "Error in Input"));

        // print the method name
        System.out.println(
            "throwable object Message = "
            + logRecord.getThrown()
                  .toString());
    }
}

Output:

throwable object Message = java.io.IOException: Error in Input

Program 2:

Java

// Java program to illustrate setThrown() method

import java.io.IOException;
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");

        // create a throwable object
        Exception exception
            = new ArithmeticException(
                "divide by 0");

        // set throwable object
        logRecord.setThrown(exception);

        // print the result
        System.out.println(
            "throwable object = "
            + logRecord.getThrown()
                  .toString());
    }
}

Output:

throwable object = java.lang.ArithmeticException: divide by 0
