LogRecord setParameters() method in Java with Examples

Last Updated : 18 Oct, 2019

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
