以下示例程序旨在说明setThrown()方法：
示例1:

// Java program to illustrate setThrown() 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.SEVERE, 
                            "Hello Logger"); 
  
        // set throwable object 
        logRecord.setThrown( 
            new IOException( 
                "Error in Input")); 
  
        // print the method name 
        System.out.println( 
            "throwable object Message = "
            + logRecord.getThrown() 
                  .toString()); 
    } 
}

输出：

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

示例2:

// Java program to illustrate setThrown() 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.SEVERE, 
                            "Hello Logger"); 
  
        // create a throwable object 
        Exception exception 
            = new ArithmeticException( 
                "divide by 0"); 
  
        // set throwable object 
        logRecord.setThrown(exception); 
  
        // print the result 
        System.out.println( 
            "throwable object = "
            + logRecord.getThrown() 
                  .toString()); 
    } 
}
