大家帮我看看这个有什么错误？

[javagodness]

// Property.java
import java.util.*;

public class Property {
public static void main(String[] args) {
System.out.println(new Date());
Properties p = System.getProperties();
p.list(System.out);
System.out.println("--- Memory Usage:");
Runtime rt = Runtime.getRuntime();
System.out.println("Total Memory = "
+ rt.totalMemory()
+ " Free Memory = "
+ rt.freeMemory());

try {
Thread.currentThread().sleep(5 * 1000);
} catch(InterruptedException e) {}
}
}

}

最后面多了一个括号

[qiyongjun2003]

catch(InterruptedException e) {}
--->
catch(InterruptedException e) {}
{
