URI getQuery() method in Java with Examples

02 Jan, 2019
The getQuery() function is a part of URI class. The function getQuery() returns the Query of a specified URI.
Function Signature
public String getQuery()
Syntax
uri.getQuery()
Parameter This function does not require any parameter
Return Type: The function returns String Type
Below programs illustrates the use of getQuery() function:
Example 1: Given a URI we will get the Query using the getQuery() function.
// Java program to show the use of the function getQuery()  import java.net.*;  class Solution {    public static void main(String args[])    {        // uri  object        URI uri = null;          try {            // create a URI            uri = new URI("https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples?title=protocol");              // get the  Query            String _Query = uri.getQuery();              // display the URL            System.out.println("URI = " + uri);              // display the  Query            System.out.println(" Query= " + _Query);        }        // if any error occurs        catch (Exception e) {            // display the error            System.out.println(e);        }    }}
URI = https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples?title=protocol
 Query= title=protocol

Example 2: Now we will not provide any query and use the function to get the query and see the results.
// Java program to show the use of the function getQuery()import java.net.*;class Solution {    public static void main(String args[])    {        // uri  object        URI uri = null;          try {            // create a URI            uri = new URI("https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples");              // get the  Query            String _Query = uri.getQuery();              // display the URL            System.out.println("URI = " + uri);              // display the  Query            System.out.println(" Query=" + _Query);        }        // if any error occurs        catch (URISyntaxException e) {            // display the error            System.out.println("URI Exception =" + e.getMessage());        }    }}

 Query=null

Example 3: The value returned by getQuery() and getRawQuery() is same except that all sequences of escaped octets are decoded.The getRawPath() returns the exact value of the string as provided by the user but the getQuery() function decodes the sequence of escaped octets if any.
// Java program to show the use of the function getQuery()import java.net.*;class Solution {    public static void main(String args[])    {        // uri  object        URI uri = null;          try {            // create a URI            uri = new URI("https://www.geeksforgeeks.org/url-getprotocol-method-in-java-with-examples?title=protocol%E2%82%AC");              // get the  Query            String _Query = uri.getQuery();              // display the URL            System.out.println("URI = " + uri);              // display the  Query            System.out.println(" Query=" + _Query);              // get the  Raw Query            String Raw_Query = uri.getRawQuery();              // display the Raw Query            System.out.println(" Raw Query=" + Raw_Query);        }        // if any error occurs        catch (URISyntaxException e) {            // display the error            System.out.println("URI Exception =" + e.getMessage());        }    }}
