Callable vs Runnable interface in Java

new Runnable() {
	public void () {
		
	}
};
		
new Callable<String>() {
	
	public String call() throws Exception {
		
		return null;
	}
};

Runnable 自JDK 1.0就有；Callable JDK 5.0
Runnable 定义任务方法是 public void run()；Callable 定义任务方法是 public call() throws Exception
run()无返回值；call返回值；
Callable 泛型接口；
Callable 可抛检查型异常；
