Java program to calculate the product of two numbers
The * operator in Java is used to multiply two numbers. Read required numbers from the user using Scanner class and multiply these two integers using the * operator.Exampleimport java.util.Scanner; public class MultiplicationOfTwoNumbers { public static void main(String args[]){ Scanner sc = new Scanner(System.in); System.out.println("Enter the value of the first number ::"); int a = sc.nextInt(); System.out.println("Enter the value of the first number ::"); int b = sc.nextInt(); int result = a*b; System.out.println("Product of the given two numbers ...

Read MoreHow to Convert Timestamp to Date in Java?
In Java, Timestamp can be converted Date by using Date class. Date class is present in java.util package. The constructor of the Date class receives a long value as an argument. Since the constructor of the Date class requires a long value, we need to convert the Timestamp object into a long value using the getTime() method of the TimeStamp class. Let's deep dive into this article, to know how it can be done by using Java programming language. To show you with instance Suppose the timestamp is 06/01/2023. Then corresponding Date is “Fri Jan ...
Read MoreJava Program to Compute the Sum of Diagonals of a Matrix
In this article, we will understand how to compute the sum of diagonals of a matrix. The matrix has a row and column arrangement of its elements. The principal diagonal is a diagonal in a square matrix that goes from the upper left corner to the lower right corner.The secondary diagonal is a diagonal of a square matrix that goes from the lower left corner to the upper right corner.Below is a demonstration of the same −Suppose our input is −The input matrix: 4 5 6 7 1 7 3 4 11 12 13 14 23 24 25 50The desired ...

Read MoreJava Program to fill an array of characters from user input
For user input, use the Scanner class with System.in. After getting the input, convert it to character array −char[] a = s.next().toCharArray();Now, display it until the length of the character array i.e. number of elements input by the user −for (int i = 0; i < a.length; i++) { System.out.println(a[i]); }To fill an array of characters from user input, use Scanner class.Exampleimport java.util.Scanner; public class Demo { public static void main(String args[]) { Scanner s = new Scanner(System.in); System.out.println("First add some characters..."); char[] a = s.next().toCharArray(); ...

To find the product of elements of an array.create an empty variable. (product)Initialize it with 1.In a loop traverse through each element (or get each element from user) multiply each element to product.Print the product.Example Live Demoimport java.util.Arrays; import java.util.Scanner; public class ProductOfArrayOfElements { public static void main(String args[]){ System.out.println("Enter the required size of the array :: "); Scanner s = new Scanner(System.in); int size = s.nextInt(); int myArray[] = new int [size]; int product = 1; System.out.println("Enter the elements of the ...
Read MoreComparing Streams to Loops in Java
Stream is a pipeline system, which is mainly used to aggregate some operations like (filter(), map(), forEach(), and collect()) in a Java environment. This function consists of a source which is followed by the value of zero and then terminate the operation. A function is an input output stream whis mainly depends on the input arguments. Every stream works when − It starts from a data source. Process the data elements through a pipeline. Terminates itself in a terminal operation. Example of Comparing Streams to Loops Here is an example − Benchmark Is Here Mode Cnt Score ...

What is Compiler Class In Java? A native code is a coding formation that can be run in a Java Virtual Machine. The compiler class, provides a support as well as give us a space to convert a Java code to a native code. This a public package which embedded in java.lang.Compiler.command() package in a Java environment. Example of a Compiler Class in Java Here is an example for a compiler class in Java − class of the NewClass$CompilerClass Name Value Is: null value Is the compilation successful here? : false value Is the compilation successful using str ...
