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.neveropen.co.za/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); } }} |
Output:
URI = https://www.neveropen.co.za/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 // 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()); } }} |
Output:
URI = https://www.neveropen.co.za/url-getprotocol-method-in-java-with-examples 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.neveropen.co.za/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()); } }} |
Output:
URI = https://www.neveropen.co.za/url-getprotocol-method-in-java-with-examples?title=protocol%E2%82%AC Query=title=protocol? Raw Query=title=protocol%E2%82%AC
