LogRecord getParameters() method in Java with Examples

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 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 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]); 
        } 
    } 
} 

Output:

java.lang.Object arg0
