Yes, it is possible to send the same parameter multiple times in HTTP requests. For example, in URL parameters, you can specify multiple values for a single key:

http://example.com/api?param=value1&param=value2&param=value3

In Java, when working with such parameters, for instance through HttpServletRequest, you can retrieve all values of a parameter using the method getParameterValues(String name), which returns an array of strings:

String[] values = request.getParameterValues("param");
for (String value : values) {
    System.out.println(value);
}

Thus, the same parameter can have multiple values, and this is supported by the HTTP standard and Java server APIs.
