下面的程序说明了 setSourceMethodName()方法: 程序 1:
// Java program to illustrate
// setSourceMethodName() 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 source method
logRecord
.setSourceMethodName(
"MyFirstSourceMethod");
// print the method name
System.out.println(
"Source method Name = "
+ logRecord.getSourceMethodName());
}
}
Output:
Source method Name = MyFirstSourceMethod
程序 2:
// Java program to illustrate
// setSourceMethodName() 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 a method from ArrayList class
// as source method
logRecord.setSourceMethodName(
ArrayList
.class
.getMethods()[0]
.getName());
// print the method name
System.out.println(
"Source method Name = "
+ logRecord.getSourceMethodName());
// now set null as method name
logRecord.setSourceMethodName(null);
// print the method name
System.out.println(
"Now new Source method Name = "
+ logRecord.getSourceMethodName());
}
}
Output:
Source method Name = add
Now new Source method Name = null
