To find the sum of such series, the Java program is as follows −Example Live Demopublic class Demo {    static long my_val = 1000000007;    public static long compute_val(long my_int){       return ((my_int % my_val) * (my_int % my_val)) % my_val;    }    public static void main(String[] args){       long my_int = 45687234;       System.out.println("The computed value is ");       System.out.print(compute_val(my_int));    } }OutputThe computed value is 335959495A class named Demo defines a function named ‘compute_val’ that computes and returns the sum of a specific series. In the main function, the ... Read More

Scala and Java are two of the most widely used high-level programming languages in the world of today's computer programming. Scala was developed specifically to address a number of Java's limitations. In particular, it is intended to be as condensed and terse as possible, with the goal of reducing the amount of code that the programmer is required to produce.Java and Scala have their own specialised fields and domains of application. Go through this article to find out the primary characteristics of these two high-level programming languages and how they are different from each other.What is Scala?Scala is a computer ...

To search a string in Matrix using split function, the code is as follows −Example Live Demoimport java.util.*; public class Demo {    public static int search_string(String[] my_matrix, String search_string){       for (String input : my_matrix){          String[] my_value = input.split(search_string);          if (my_value.length >= 2 || my_value.length == 0){             return 1;          }          else if (my_value.length == 1 && input.length() != my_value[0].length()){             return 1;          }       } ...

JavaJava is an object oriented programming language as well as a computing platform.It is safe, quick and reliable.The code in Java is first converted into bytecode and then executed using a JVM (Java Virtual Machine).The java program that is converted into bytecode is stored with the help of the extension ‘.class’.Java doesn’t give any specific way in which associative arrays could be stored, instead there are implementations of various hash functions.Java programs that need to be run are stored with the extension ‘.java’.Java is a statically typed language, i.e type checking is performed during compile-time (not run-time).Single line comments in ...

In general, 10 packages are imported using the JShell.The following command shows the packages that were imported by default.jshell> /importOutputimport java.io.* import java.math.* import java.net.* import java.nio.file* import java.sql.* import java.util.* import java.util.regex* import java.util.function* import java.util.prefs* import java.util.stream.*Importing a specific package using JShelljshell> import java.util.*;

There are ambiguities while using variable arguments in Java. This happens because two methods can definitely be valid enough to be called by data values. Due to this, the compiler doesn’t have the knowledge as to which method to call.Example Live Demopublic class Demo {    static void my_fun(double ... my_Val){       System.out.print("fun(double ...): " + "Number of args: " + my_Val.length );       for(double x : my_Val)       System.out.print(x + " ");       System.out.println();    }    static void my_fun(boolean ... my_Val){       System.out.print("fun(boolean ...) " + "The number of ... Read More

To input multiple values from user in one line, the code is as follows −Example Live Demoimport java.util.Scanner; public class Demo {    public static void main(String[] args) {       System.out.print("Enter two floating point values : ");       Scanner my_scan = new Scanner(System.in);       double double_val = my_scan.nextFloat();       int int_val = my_scan.nextInt();       System.out.println("The floating point value is : " + double_val + " and the integer value is : "       + int_val);    } }Input56.789 99OutputEnter two floating point values : The floating point value is ...

The ‘interrupt’ function can be used in Java to interrupt the execution of a thread with the help of the exception InterruptedException.The below example shows how the currently executing thread stops execution (because of a new exception raised in the catch block) once it is interrupted −Example Live Demopublic class Demo extends Thread {    public void run()    {       try       {          Thread.sleep(150);          System.out.println("In the 'run' function inside try block");       }       catch (InterruptedException e)       {       ...

To get sum of list with stream filter in Java, the code is as follows −Example Live Demoimport java.util.*; public class Demo {    public static void main(String[] args)    {       List my_list = new ArrayList();       my_list.add(11);       my_list.add(35);       my_list.add(56);       my_list.add(78);       my_list.add(91);       System.out.println(sum(my_list));    }    public static int sum(List my_list)    {       System.out.println("In the main function, the sum of list with filter is ");       return my_list.stream().filter(i -> i > 5).mapToInt(i -> i).sum();    } ...

While writing any piece of code in Java, there is a certain set of rules and regulations that need to be followed, that is considered as a standard. For example − A class contains variables, and functions. The functions can be used to work with the variables. Classes can be extended, and improvised too.Basic structureList of packages that are imported; public class {    Constructor (can be user defined or implicitly created)    {       Operations that the constructor should perform;    }    Data elements/class data members;    User-defined functions/methods;    public static void main (String ...
