The removeLast() method of the java.util.LinkedList class removes and returns the last element of this list.Example:import java.util.*; public class LinkedListDemo { public static void main(String[] args) { LinkedList list = new LinkedList(); list.add("Hello"); list.add(2); list.add("Chocolate"); list.add("10"); System.out.println("LinkedList:" + list); System.out.println("Last element:" + list.removeLast()); System.out.println("LinkedList:" + list); } }Output:LinkedList:[Hello, 2, Chocolate, 10] Last element:10 LinkedList:[Hello, 2, Chocolate]
Persistence layer is used in case of system failure, database corruption or power failure to restore the database to most recent save point in HANA. Persistence Layer is responsible for data and transaction log backup and also to store configuration of HANA system.Backup of data and transaction log files are taken as per Backup settings in HANA system configuration. It can be set to minutes, Hours and days and destination of backup is also defined under Backup settings.When a backup is run for data and transaction files, system takes the backup from all the servers in HANA system.Persistence Layer is ...

String-valued functions return NULL if the length of the result would be greater than the value of the max_allowed_packet system variable. Actually, max_allowed_packet is a dynamic global variable which can accept the integer type values. These values can be set for a session only. It can accept 1024 as the minimum value and 1073741824 as the maximum value. The by the default value of this system variable is 1048576.
The purpose of a while loop is to execute a statement or code block repeatedly as long as an expression is true. Once the expression becomes false, the loop terminates. Let’s see how to show while loop using flowchart in JavaScript −
Preprocessor server provides text data analysis and search capabilities in HANA system. Preprocessor server is used by Index search to analyze the text data and to perform any search on the text data. This server is used to extract the information based on text search capabilities in HANA system.
Statistics server is used to manage health of your HANA system. You can take information related to status, performance consumption of resources from all the servers in your system landscape. You can also pull the reports related to performance of server components for analysis.
The Collections class provides a method named reverse() this method accepts a list and reverses the order of elements in it.Example:import java.util.ArrayList; import java.util.Collections; import java.util.LinkedHashSet; import java.util.Set; public class Sample { public static void main(String[] args){ ArrayList list = new ArrayList(); list.add("JavaFx"); list.add("Java"); list.add("WebGL"); list.add("OpenCV"); Set set = new LinkedHashSet(list); System.out.println(set); Collections.reverse(list); System.out.println(list); } }Output:[JavaFx, Java, WebGL, OpenCV] [OpenCV, WebGL, Java, JavaFx]
Following are the various constructors provided by the StringBuffer class.S.N.Constructor & Description1StringBuffer()This constructs a string buffer with no characters in it and an initial capacity of 16 characters.2StringBuffer(CharSequence seq)This constructs a string buffer that contains the same characters as the specified CharSequence.3StringBuffer(int capacity)This constructs a string buffer with no characters in it and the specified initial capacity.4StringBuffer(String str)This constructs a string buffer initialized to the contents of the specified string.
To perform a reverse toggle split the words of a string, reverse each word using the split() method, change the first letter of each word to lower case and remaining letters to upper case.Example Live Demoimport java.lang.StringBuffer; public class ToggleReverse { public static void main(String args[]){ String sample = "Hello How are you"; String[] words = sample.split(" "); String result = ""; for(String word:words){ StringBuffer s = new StringBuffer(word); word = s.reverse().toString(); String firstSub = word.substring(0, 1); String secondSub = word.substring(1); result = result+firstSub.toLowerCase()+secondSub.toUpperCase()+" "; } System.out.println(result); } }OutputoLLEH wOH eRA uOY
SAP HANA system combines OLAP and OLTP processing into a single in-memory database and it removes the disk bottlenecks and offering groundbreaking performance. This ACID-compliant, in-memory columnar database stores provides data compression up to 11 times as compared to other conventional database, parallel processing across multiprocessor cores, and supports single instruction multiple data (SIMD) commands.
