Java Program to Print Square Star Pattern
In this article, we will understand how to print square star pattern. The pattern is formed by using multiple for-loops and print statements.Below is a demonstration of the same −InputSuppose our input is −Enter the length of a side : 8OutputThe desired output would be −The square pattern : * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ...
Read MoreSearch and Replace with Java regular expressions
Java provides the java.util.regex package for pattern matching with regular expressions. Java regular expressions are very similar to the Perl programming language and very easy to learn.A regular expression is a special sequence of characters that help you match or find other strings or sets of strings, using a specialized syntax held in a pattern. They can be used to search, edit, or manipulate text and data.The replaceFirst() and replaceAll() methods replace the text that matches a given regular expression. As their names indicate, replaceFirst replaces the first occurrence, and replaceAll replaces all occurrences.Exampleimport java.util.regex.Matcher; import java.util.regex.Pattern; public class RegexMatches { ...

The pattern is formed by using multiple for-loops and print statements.Below is a demonstration of the same −InputSuppose our input is −Enter the size : 5OutputThe desired output would be −The spiral pattern 5 5 5 5 5 5 5 5 5 5 4 4 4 4 4 4 4 5 5 4 3 3 3 3 3 4 5 5 3 2 2 4 2 3 4 5 5 4 3 2 1 2 3 4 5 5 4 3 2 2 2 3 4 5 ...
Read MoreJava Program to Print a String
In this article, we will understand how to print a string in Java. A string is a pattern of characters and alphanumeric values. The easiest way to create a string is to write −String str = "Welcome to the club!!!"Whenever it encounters a string literal in your code, the Java compiler creates a String object with its value in this case, " Welcome to the club!!!'.As with any other object, you can create String objects by using the new keyword and a constructor. The String class has 11 constructors that allow you to provide the initial value of the string ...
Read MoreJava Program to Check if two of three Boolean variables are true
In this article, we will learn to check if any two out of three boolean values are true or not. Boolean variables are datatypes that contain only true or false values. Below is a demonstration of the same - Input: true, true, falseOutput : Two of the three variables are true Checking if two of three Boolean variables are trueIn this article, we will discuss two approaches to check it, and they are - Using if-else Condition ...
Read MoreWhat are C++ Floating-Point Constants?
Floating-point constants specify values that must have a fractional part.Floating-point constants have a "mantissa, " which specifies the value of the number, an "exponent, " which specifies the magnitude of the number, and an optional suffix that specifies the constant's type(double or float).The mantissa is specified as a sequence of digits followed by a period, followed by an optional sequence of digits representing the fractional part of the number. For example −24.25 12.00These values can also contain exponents. For example, 24.25e3 which is equivalent to 24250In C++ you can use the following code to create a floating point constant −Example#include ...

In this article, we will understand how to print inverted star pattern. The pattern is formed by using multiple for-loops and print statements.Below is a demonstration of the same −InputSuppose our input is −Enter the size : 8OutputThe desired output would be −The inverted star pattern *************** ************* *********** ********* ******* ***** *** *AlgorithmStep 1 - START Step 2 - Declare four integer values namely i, j, k and my_input. Step 3 ...
Read MoreJava Program to Round a Number to n Decimal Places
In this article, we will understand how to round a number to n decimal places. Rounding of decimal values are done using the CEIL or FLOOR functions.Below is a demonstration of the same −InputSuppose our input is −Input : 3.1415OutputThe desired output would be −Output : 3.2 AlgorithmStep 1 - START Step 2 - Declare a float variable values namely my_input. Step 3 - Read the required values from the user/ define the values Step 4 – Use the CEIL function to round the number to the required decimal places. In this example we are rounding up to 2 decimal ...
Read MoreJava Program to Print Hollow Right Triangle Star Pattern
In this article, we will understand how to print hollow right triangle star pattern. The pattern is formed by using multiple for-loops and print statements. For the pyramid at the first line it will print one star, and at the last line it will print n number of stars. For other lines it will print exactly two stars at the start and end of the line, and there will be some blank spaces between these two starts.Below is a demonstration of the same −InputSuppose our input is −Enter the size : 8OutputThe desired output would be −The hollow pyramid triangle ...
Read MoreJava Program to Generate Multiplication Table
In this article, we will understand how to print a multiplication table. Multiplication table is created by iterating the required input 10 times using a for loop and multiplying the input value with numbers from 1 to 10 in each iteration.Below is a demonstration of the same −InputSuppose our input is −Input : 16OutputThe desired output would be −The multiplication table of 16 is : 16 * 1 = 16 16 * 2 = 32 16 * 3 = 48 16 * 4 = 64 16 * 5 = 80 16 * 6 = 96 16 * 7 = 112 ...
