What is the difference between throws and try...catch in java?

throws is to throw an exception and subsequent code will not be executed. And try...catch throws the exception and continues to execute the following code.

package com.oracle;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Demo01Exception {
      /*Exception：编译期间异常，进行编译（写代码的过程）
       *  runtimeException:运行期异常，java程序运行过程中出现的问题     
       *Error:错误(出现的错误无法调试，必须修改源代码)
       *  
       */
	public static void main(String[] args){
		//*Exception：编译期间异常，进行编译（写代码的过程）
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");//格式化日期对象。
		Date date =null;
		try {
			date = sdf.parse("1999-0909");
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}//把字符串格式的日期，解析为Date格式日期
		System.out.println(date);
		System.out.println("kkkkk");
	}
}
