persistent in serialization keyword geek for geeks in java code example

Example 1: a["default"].serialize(n)

var paramObj = {};
$.each($('#myForm').serializeArray(), function(_, kv) {
  if (paramObj.hasOwnProperty(kv.name)) {
    paramObj[kv.name] = $.makeArray(paramObj[kv.name]);
    paramObj[kv.name].push(kv.value);
  }
  else {
    paramObj[kv.name] = kv.value;
  }
});

Example 2: Serialization and Deserialization

Serialization; when we MAP a Java object to API JSON
format (CONVERT JAVA OBJECT TO JSON);

Deserialization; API JSON/XML ^ MAP it to Java Object
(JSON TO JAVA OBJECT)
