Check if Array is Free From 0 and Negative Number in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to check and confirm the array is free from 0 and negative numbers. Let us say that an array contains 0 or a negative element then the result should pop up that "Array contains 0 or a negative number." Otherwise, the result should be "Array doesn’t contain 0 or a negative number." Note − The array must be an integer array. Let’s explore the article to see how it can be done by using ...
Read MoreArrange Negative Array Elements Before Positive Elements in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to arrange all elements of array such that negative elements are present before positive elements. If a number is greater than 0 then it is called as positive number, if less than 0 then it is called as negative number. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the ...
Read MoreJAVA Program to Replace Element of Integer Array with Product of Other Elements
Array of Integers refers to an array where all the elements are of Integer type. It is alsocalled an Integer array. As per the problem statement we have to create an Integer array and display the array elements where all the array elements are the product of other elements of the array. In this article, we will see how to replace array elements by the product of other array elements by using Java programming language. To show you some instances − Instance-1 int arr[] = { 2, 3, 1, 4, 6 } At Index-0 value will be = 3 * ...
Read MoreJAVA Program to Calculate Radius of Circle with Given Width and Height of Arc
A circle is a round shape two-dimensional diagram which has no corners. Every circle has an origin point and every point on the circle maintains equal distance from the origin. The distance between the origin and a point in a circle is known as Radius of the circle. And similarly, if we draw a line from one edge to another edge of the circle and the origin is held in the middle of it, that line is known as diameter of the circle. Basically, the diameter is double of the length of the radius. Arc of the circle refers ...
Read MoreJava Menu Driven Program to Perform Basic String Operations
String refers to a sequence of characters. In Java Strings are objects. To create and manipulate strings Java provides the String class. String class has many inbuilt methods which are used for different purposes. We will perform a few basic string operations by using inbuilt String methods. replace() Method: It replaces a specified character in the given string. concat() Method: It appends another string to the end of one string. length() Method: It returns the length of the given String. Equals() Method: It checks whether two strings are equal or not. In this article, we will see some basic ...
Read MoreJava Program to Enter a Number in Digit and Display in Words
Digits are basically represented in number format or these are integer values. But for pronouncing them we are using words. Every digit has a unique word format. For example, the word format of 1 is “One”. Like that for 2 the word format is “two”, for 3 the word format is “three” ... etc. For two-digit number the number format is little different. 21 represents as “twenty-one”, 45 represents as “forty-five” .... etc. So for all type of number there has a unique word format available. To show you some instances Instance-1 Input number is 15. Word format of 15 ...
Read MoreJava Menu Driven Program to Perform Array Operation
Array in Java is called as a non primitive data type which stores a fixed number of single type values. It is called a One-dimensional array. In this article, we will see how to perform different array operations like checking duplicate elements, printing array in reverse order, checking largest element, checking smallest element, finding sum of all array elements by using Java Menu driven program. We will be implementing the application using a switch case. To show you some instances − Instance-1 Suppose we have created an array containing 6 elements and array elements are [2, 4, 6, 2, 6, ...
Read MoreJava Menu Driven Program to Determine Cost of New Membership
When we go anywhere for any type of membership they have different prices for different plans. For example silver membership, gold membership, diamond membership, platinum membership etc. where the silver membership costs less than others and platinum membership costs more than other plans. In this article we will see how to check the cost of a membership by using the Java programming language. We will be implementing the application using a switch case. To show you some instances Instance-1 Suppose we have Rs 1840 as base membership price and you want to have a silver membership. The cost of silver ...
Read MoreJava Menu Driven Program to Check Type of a Number
In Java we have primitive numeric data types for numbers that are short, byte, int, long, float and double. These numeric data types allow us to represent different integer and real numbers based on their range as a specific data type has its lower and upper range. Below are the 6 primitive numeric data types byte: Range -128 to 127 (Size 1 byte) short: Range -32, 768 to 32, 767 (Size 2 bytes) int: Range -2, 147, 483, 648 to 2, 147, 483, 647 (Size 4 bytes) long: Range -9, 223, 372, 036, 854, 775, 808 to 9, 223, 372, ...

A circle is a round shape two-dimensional diagram which has no corners. Every circle has an origin point and every point on the circle maintains equal distance from the origin. The distance between the origin and a point in a circle is known as Radius of the circle. And similarly, if we draw a line from one edge to another edge of the circle and the origin is held in the middle of it, that line is known as diameter of the circle. Basically, the diameter is double of the length of the radius. A square consists of four sides ...
