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
