@SuppressWarnings ("deprecation")

There are a lot of warnings during the Java compilation process, many of which are secure, but there are a lot of warnings for each compilation that affect our filtering and modification of error, and we can add

@SuppressWarnings ("XXXX") to resolve

@SuppressWarnings ("deprecation") means not to detect whether the following method is enabled.

For example:

public void DoPost (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException {
Request.setcharacterencoding ("Utf-8");
Response.setcontenttype ("Text/html;charset=utf-8");
User U=new user ();
U.setuname (Request.getparameter ("Uname"));
U.setupwd (Request.getparameter ("upwd"));
U.setaddress (Request.getparameter ("Address"));
String temp[]=request.getparameter ("Birthday"). Split ("-");
@SuppressWarnings ("deprecation")
Date Date =new date (Integer.parseint (temp[0)) -1900,integer.parseint (temp[1]) -1,integer.parseint (temp[2])); //This sentence should have a warning indicating that this method is obsolete.
