I guess that your Dateclass is actually a java.sql.Date.
我猜你的Date班级实际上是一个java.sql.Date.

DateFormat.parse()returns an instance of java.util.Dateand not java.sql.Date.
In order to convert from java.util.Dateto java.sql.Date, I do the following:
DateFormat.parse()返回java.util.Date和 not的实例java.sql.Date。为了从 转换java.util.Date为java.sql.Date，我执行以下操作：
java.util.Date fromDate = df.parse(fromdate1);
java.sql.Date sqlDate = new java.sql.Date(fromDate.getTime());

What does your import statement say? Are you importing some other class (for example java.sql.Date) by accident? What does the compiler say when you remove the class cast (which should not be there)?
你的进口声明说什么？您是否java.sql.Date意外导入了其他类（例如）？当您删除类强制转换（不应该在那里）时，编译器会说什么？

It simply means you are assigning java.util.Datein java.sql.Date
它只是意味着你要分配 java.util.Date在java.sql.Date
From your example you have to do following :
从您的示例中，您必须执行以下操作：
String str = "13/06/2011";
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
java.util.Date date = (java.util.Date)formatter.parse( str );
