Java Program to Print Half Diamond Star Pattern
In this article, we will understand how to print half diamond 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 number of rows : 8OutputThe desired output would be −The half diamond pattern : * ** *** **** ***** ****** ******* ******** ******* ****** ***** **** *** ** *AlgorithmStep 1 - START Step 2 - Declare three integer values namely i, j and my_input Step 3 - Read the required values from the user/ define the values Step 4 - We iterate through two ...

Read MoreJava Program to Make a Simple Calculator Using switch...case
In this article, we will understand how to construct a simple calculator using switch-case. The switch statement evaluates an expression, matching the expression's value to a case clause, and executes statements associated with that case.Following are the arithmetic operations we are going to perform.AdditionSubtractionMultiplicationDivisionFloor DivisionModuloBelow is a demonstration of the same −InputSuppose our input is −The two inputs: 40.0 and 12.0 Operator:%OutputThe desired output would be −The result is 40.0 % 12.0 = 4.0AlgorithmStep 1 - START Step 2 - Declare three values namely my_input_1, my_input_2 and my_result and declare a character value namely operator. Step 3 - Read the required ...
Read MoreJava Program to pass method call as arguments to another method
In this article, we will understand how to pass method call as arguments to another method. We can call a method from another class by just creating an object of that class inside another class. After creating an object, call methods using the object reference variable.Below is a demonstration of the same −InputSuppose our input is −Enter two numbers : 2 and 3OutputThe desired output would be −The cube of the sum of two numbers is: 125AlgorithmStep 1 - START Step 2 - Declare two variables values namely my_input_1 and my_input_2 Step 3 - We define a function that takes ...
Read MoreCheck if a binary string contains all permutations of length k in C++
Suppose we have a binary string, another integer k. We have to check the string is containing all permutations of binary of k bits. Suppose a string is like “11001”, and if the K = 2, then it must have all permutations of k bit numbers. (00, 01, 10, 11), the given string has all permutation. So this is valid string.by taking the binary string and the value of k, we have to check whether binary sequences are matched or not. The binary sequence is made of size k. So there will be 2k number of different binary permutations. We ...
Read MoreString Concatenation by concat() method.
You can concatenate two strings using the concat() method of the String class. This class concatenates the specified string to the end of this string.Examplepublic class Test { public static void main(String args[]){ String str1 = "Krishna"; String str2 = "Kasyap"; System.out.println(str1.concat(str2)); } }OutputkrishnaKasyap

Below is a demonstration of the same − Input Suppose our input is − Enter the number of rows : 8 Output The desired output would be − The pyramid star pattern : * * * * * * * * * * * * * * * * ...
Read MoreHow to find the vowels in a given string using Java?
You can read a character in a String using the charAt() method. To find the vowels in a given String you need to compare every character in it with the vowel letters. Example public class FindingVowels { public static void main(String args[]) { String str = new String("Hi Welcome to Tutorialspoint"); for(int i=0; i
Read MoreHow to find consonants in a given string using Java?
One way to find the vowels in a given String is to compare every character in it using the charAt() method with the vowel letters. Example public class FindingConsonants { public static void main(String args[]) { String str = new String("Hi Welcome to Tutorialspoint"); for(int i=0; i
