A block of code that is associated with the static keyword is called as static block. This block executes when classloader loads the class. Remember, if your code contains any static block, it will be invoked before the main() method. In this article, we will learn how to create and invoke static blocks in Java along with its use case. But, before that let's understand the static keyword. What is Static Keyword? The static keyword in Java is a non-access modifier. This keyword is used with variables, methods, blocks of code and classes. A class, method or variable declared with ... Read More

Following is the Java program for Standard Normal Distribution −Example Live Demoimport java.io.*; import java.util.*; public class Demo{    public static void main(String[] args){       double std_dev, val_1, val_3, val_2;       val_1 = 68;       val_2 = 102;       val_3 = 26;       std_dev = (val_1 - val_2) / val_3;       System.out.println("The standard normal deviation is: " + std_dev);    } }OutputThe standard normal deviation is: -1.3076923076923077A class named Demo contains the main function, where certain double values are defined, and the formula for standard deviation is applied ((val_1 - val_2) / val_3) on these values and the resultant output is displayed on the console.

In this article, we will learn how to replace a specific word in a sentence with asterisks using Java. This technique can be useful for obscuring certain words in a text for privacy or censorship purposes. Problem Statement Develop a program in Java that takes a sentence and a word to be censored as input, then outputs the sentence with the specified word replaced by asterisks, while preserving the original format of the sentence. Input This is a sample only, the sky is blue, water is transparent Output This is a ****** only, the sky is blue, water is transparent ... Read More

In Java, checking if a string contains special characters can be easily done using regular expressions. We will be using the Pattern and Matcher classes from the java.util.regex package, we can efficiently determine whether a string includes any special characters. In this article, we will demonstrate how to use these classes to perform the check and handle the result accordingly. − Problem Statement For a given string write a Java program to check if it contains any special character or not − Input 1 I Love Tutorialspoint Output 1 Special character not found in the string Input 2 ...

Following is the Java program for Stooge sort −Example Live Demoimport java.io.*; public class Demo {    static void stooge_sort(int my_arr[], int l_val, int h_val){       if (l_val >= h_val)       return;       if (my_arr[l_val] > my_arr[h_val]){          int temp = my_arr[l_val];          my_arr[l_val] = my_arr[h_val];          my_arr[h_val] = temp;       }       if (h_val-l_val+1 > 2){          int temp = (h_val-l_val+1) / 3;          stooge_sort(my_arr, l_val, h_val-temp);          stooge_sort(my_arr, l_val+temp, h_val);   ...

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 ...
