URIgetRawAuthority() method in Java, example
URI getRawAuthority() method in Java, examples Original text: https://www . geesforgeks . org/uri-getrawauthority-method-in-Java-with-examples/ getRawAuthority() The function is part of the URI class. The function getRawAuthority() returns the original authority of the specified URI. This function returns the hostname and the exact value of post without decoding the escape octet sequence (if any). Function signature: public String getRawAuthority() Syntax: url.getRawAuthority() ParametersThis function does not require any parameters Return typeThe function returns String type, which is the exact value of the host name The following program illustrates the use of the getRawAuthority() function: Example 1: // Java program to show the// use of the function getRawAuthority()import java.net.*;class GFG {public static void main(String args[]) { // URI object URI uri = null; try { span> uri = new URI( ”https://www.geeksforgeeks.org”); // get the raw Authority String raw_authority span>getRawAuthority(); // display the URI System.out .println(“URI = ” + uri); display the Raw Authority System.out .println(“Raw Authority = ” + raw_authority); span> (Exception e) { // display the error System.out. println(e); } }} Output: URI = https://www.geeksforgeeks.org Raw Authority = www.geeksforgeeks.org Example 2:The difference between getRawAuthority() and getHost() functions is that getRawAuthority() returns host and port, while getHost() only returns the host name. // Java program to show the// use of the function getRawAuthority() static void main(String args[]) { // url…
PathgetParent() method in Java, example
Path getParent() method in Java, examples Original text: https://www . geesforgeks . org/path-getparent-method-in-Java-with-examples/ Java NIO in Java 7 adds the Java Path Interface. The Path interface is located in the java.nio.file package, so the fully qualified name of the Java Path interface is Java . nio . file . Path. A Java Path instance represents a path in the file system. Paths can be used to locate files or directories. The path of an entity can be of two types: one is an absolute path and the other is a relative path. An absolute path is a location address from the root to an entity, while a relative path is a location address relative to other paths. getParent() method’s java.nio.file.Path is used to return the parent path of the current path object, if the path has no parent path is null. The parent path of this path object consists of the root component of this path and every element in the path except the element furthest from the root in the directory hierarchy. If this path has multiple elements and has no root component, this method is equivalent to evaluating the expression: subpath span>(0, getNameCount ()-1); Syntax: Path getParent() Parameters:This…

Buffered array() method in Java, example
Buffer array() method in Java, examples Original text: https://www . geesforgeks . org/buffer-array-methods-in-Java-with-examples/ The array() method of the java.nio.Buffer class is used to return an array that supports the buffer taken. This method is intended to allow array-backed buffers to be passed to native code more efficiently. Concrete subclasses provide a stronger type of return value for this method. Modifications to the contents of this buffer will cause the contents of the returned array to be modified, and vice versa. Before calling this method, call the hasArray method to ensure that this buffer has an accessible backing array. Syntax: public abstract Object array() Return value:This method returns the array supporting this buffer. Exception: If this buffer is backed by an array but is read-only, this method throws a readonlybufferrexception. The following is an example illustrating the array() method: Example 1: // Java program to demonstrate// array() methodimport java.nio.*;import java.util.*;public class GFG { public static void main (String[] args) { // Declaring the capacity of the ByteBuffer int capacity = 4; // Creating the ByteBuffer try { // creating object of ByteBuffer // and allocating size capacity ByteBuffer bb = ByteBuffer.allocate( capacity); // putting the int to byte typecast span class=”na”>put((byte)20); p”>.put((byte)30); .put((byte)40); bb.put((byte)50 ); // Typecasting ByteBuffer into Buffer Buffer…
