certainly! the `uribuilder` class in java is part of the apache httpcomponents library, specifically in the `httpclient` package. it is used to construct uri (uniform resource identifier) objects in a convenient way, allowing you to create uris with various components like scheme, host, port, path, query parameters, and so on.

tutorial on java uribuilder

#### 1. *setting up your environment*

to use `uribuilder`, you need to include the apache httpcomponents library in your project. if you are using maven, you can add the following dependency to your `pom.xml`:



if you are not using maven, you can download the jar files from the [apache httpcomponents website](https://hc.apache.org/downloads.cgi) and add them to your project's classpath.

#### 2. *basic usage of uribuilder*

here’s a simple example of how to use `uribuilder` to construct a uri:



explanation of the code:

1. **importing required classes**: we import `uribuilder` and `uri` classes from the apache httpcomponents and `urisyntaxexception` from the java standard library.

2. **creating uribuilder instance**: we create an instance of `uribuilder`.

3. **setting uri components**:
`setscheme("https")`: sets the scheme of the uri (e.g., `http`, `https`).
`sethost("www.example.com")`: sets the host (domain) part of the uri.
`setport(443)`: sets the port number (443 is the default for https).
`setpath("/search")`: sets the path of the uri.
`setparameter("query", "java uri builder")`: adds a query parameter to the uri.
`setparameter("page", "1")`: adds another query parameter.

4. **building the uri**: the `build()` method constructs the final uri object.

5. **printing the uri**: finally, we print the constructed uri.

output:

when you run the above code, it will output:



3. *additional features*

**adding multiple parameters**: you can add multiple values to the same parameter by calling `addparameter()` instead of `setparameter()`.
