-## Intent
-
-The syntax of Java language doesn’t allow you to declare a method with a predefined value
-for a parameter. Probably the best option to achieve default method parameters in Java is
-by using the method overloading. Method overloading allows you to declare several methods
-with the same name but with a different number of parameters. But the main problem with
-method overloading as a solution for default parameter values reveals itself when a method
-accepts multiple parameters. Creating an overloaded method for each possible combination of
-parameters might be cumbersome. To deal with this issue, the Parameter Object pattern is used.
-
-## Explanation
-
-The Parameter Object is simply a wrapper object for all parameters of a method.
-It is nothing more than just a regular POJO. The advantage of the Parameter Object over a
-regular method parameter list is the fact that class fields can have default values.
-Once the wrapper class is created for the method parameter list, a corresponding builder class
-is also created. Usually it's an inner static class. The final step is to use the builder
-to construct a new parameter object. For those parameters that are skipped,
-their default values are going to be used.
-
-
-**Programmatic Example**
-
-Here's the simple `SearchService` class where Method Overloading is used to default values here. To use method overloading, either the number of arguments or argument type has to be different.
-
-```java
-public class SearchService {
-  //Method Overloading example. SortOrder is defaulted in this method
-  public String search(String type, String sortBy) {
-    return getQuerySummary(type, sortBy, SortOrder.DESC);
-  }
-
-  /* Method Overloading example. SortBy is defaulted in this method. Note that the type has to be 
-  different here to overload the method */
-  public String search(String type, SortOrder sortOrder) {
-    return getQuerySummary(type, "price", sortOrder);
-  }
-
-  private String getQuerySummary(String type, String sortBy, SortOrder sortOrder) {
-    return "Requesting shoes of type \"" + type + "\" sorted by \"" + sortBy + "\" in \""
-        + sortOrder.getValue() + "ending\" order...";
-  }
-}
-
-```
-
-Next we present the `SearchService` with `ParameterObject` created with Builder pattern.
-
-```java
-public class SearchService {
-
-  /* Parameter Object example. Default values are abstracted into the Parameter Object 
-  at the time of Object creation */
-  public String search(ParameterObject parameterObject) {
-    return getQuerySummary(parameterObject.getType(), parameterObject.getSortBy(),
-        parameterObject.getSortOrder());
-  }
-  
-  private String getQuerySummary(String type, String sortBy, SortOrder sortOrder) {
-    return "Requesting shoes of type \"" + type + "\" sorted by \"" + sortBy + "\" in \""
-        + sortOrder.getValue() + "ending\" order...";
-  }
-}
-
-public class ParameterObject {
-  public static final String DEFAULT_SORT_BY = "price";
-  public static final SortOrder DEFAULT_SORT_ORDER = SortOrder.ASC;
-
-  private String type;
-  private String sortBy = DEFAULT_SORT_BY;
-  private SortOrder sortOrder = DEFAULT_SORT_ORDER;
-
-  private ParameterObject(Builder builder) {
-    type = builder.type;
-    sortBy = builder.sortBy != null && !builder.sortBy.isBlank() ? builder.sortBy : sortBy;
-    sortOrder = builder.sortOrder != null ? builder.sortOrder : sortOrder;
-  }
-
-  public static Builder newBuilder() {
-    return new Builder();
-  }
-
-  //Getters and Setters...
-
-  public static final class Builder {
-
-    private String type;
-    private String sortBy;
-    private SortOrder sortOrder;
-
-    private Builder() {
-    }
-
-    public Builder withType(String type) {
-      this.type = type;
-      return this;
-    }
-
-    public Builder sortBy(String sortBy) {
-      this.sortBy = sortBy;
-      return this;
-    }
-
-    public Builder sortOrder(SortOrder sortOrder) {
-      this.sortOrder = sortOrder;
-      return this;
-    }
-
-    public ParameterObject build() {
-      return new ParameterObject(this);
-    }
-  }
-}
-
-
-```

-
-## Applicability
-
-This pattern shows us the way to have default parameters for a method in Java as the language doesn't default parameters feature out of the box.
