请看下面的程序对系统资源的占用如何？(50分)

import java.util.Date;
class TestWait
{
public static void main(String[] args)
{
while(true)
{
System.out.println("Current time: " + new Date());
TestWait obj = new TestWait();
synchronized(obj)
{
try
{
obj.wait(1000);
}
catch(Exception e)
{
System.out.println("caught exception");
}
}
}
}
}
