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
// 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());
}
}
} |
URI = https://www.geeksforgeeks.org/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.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());
}
}
