// getThrown() 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.INFO, 
                            "GFG Logger"); 
        logRecord.setThrown( 
            new IOException( 
                "Error in Input")); 
  
        // get Throwable object 
        Throwable throwObj 
            = logRecord.getThrown(); 
  
        // print result 
        System.out.println( 
            "throwable object = "
            + throwObj 
                  .toString()); 
    } 
}

输出：

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

示例2:

// Java program to illustrate 
// getThrown() method 
  
import java.util.logging.Level; 
import java.util.logging.LogRecord; 
  
public class GFG {

    { 
  
        // Create LogRecord object 
        LogRecord logRecord

                            "Logger"); 
        logRecord.setThrown( 
            new ArithmeticException()); 
  
        // get Throwable object 
        Throwable throwObj 
            = logRecord.getThrown(); 
  
        // print result 
        System.out.println(
