//String转换为java.util.Date

String str = "2013-01-14";

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

Date date = null; //初始化date

try {

date = sdf.parse(str); //Mon Jan 14 00:00:00 CST 2013

} catch (ParseException e) {

e.printStackTrace();

}
//String转换为java.util.Date
String str = "2013-01-14";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date date = null; //初始化date
try {
date = sdf.parse(str); //Mon Jan 14 00:00:00 CST 2013
} catch (ParseException e) {
e.printStackTrace();
}

String pattern = "yyy-MM-dd HH:mm:ss"; //首先定义时间格式
SimpleDateFormat format = new SimpleDateFormat(pattern);//然后创建一个日期格式化类
String toConvertString = "2012-11-01 10:10:05";
Date convertResult = null;
try {
convertResult = format.parse(toConvertString);
} catch (ParseException e) {
e.printStackTrace();
}
System.out.println(convertResult);
执行结果为
Thu Nov 01 10:10:05 CST 2012
