JAVA Program To Convert Roman Number to Integer Number
Roman Number − Based on the ancient Roman system, symbols are used to represent the numbers. These numbers are known as Roman numbers. Symbols are I, V, X, L, C, D, and M use respectively for 1, 5, 10, 50, 100, 500, and 1, 000. Integer Number − Integer number is nothing but the whole number which consists ofpositive, negative and zero value. Fraction numbers are not integers. Here we have set the symbol values as per their integer values. Whenever a roman number is entered as input we divide into units and then calculate the appropriate roman number. I ...
Read MoreCheck Whether a Number is an Autobiographical Number or Not in JAVA
A number is said to be an Autobiographical number, if the number’s first digit represents the number of 0 available in the given number, the second number represents the number of 1 present in the given number, the third number represents the number of 2 present in the given number and so on. In simple terms, if the given number’s digits from left to right represent the frequency of 0, 1, 2, 3, 4.... N respectively present in the given number then that number is known as Autobiographical number. Some examples of Autobiographical numbers are: 1210, 2020, 21200, 3211000, 42101000 ...
Read MoreCheck Whether a Number is a Coprime Number or Not in Java
Two numbers are said to be Coprime numbers, if the maximum common divisors is 1 for those two numbers. For more clarification, there might be multiple divisors for any number and in some scenarios, there are some common divisors that are also present between two number’s divisors. So, if in any case we get the maximum common divisors between two numbers are 1, then those two numbers are known as coprime numbers. Simply, it means those numbers do not have any other common factors other than 1. In other words, we can say that these two numbers are mutually prime ...
Read MoreJAVA Program to Calculate Shortest Distance from Center of the Circle to Chord
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. Chord of the circle refers to ...

Read MoreHow To Check Whether a Number is Tech Number or Not in Java?
A number is said to be a tech number, when an even digit number is divided into exactly two parts and the square value of the sum of those two numbers is equal to the original number. For more clarification, we take a number which has even digits. After that, divide it into two parts and add two parts. After getting the sum value, we calculate the square of it. Now we compare both the calculated square value and the original/input number. If both are same then we can say that the input number is a tech number otherwise ...
Read MoreHow To Check Whether a Number is Tcefrep Number or Not in Java?
A number is said to be a Tcefrep number, if the reverse of that number is equal to the sum of the proper divisors of the original number. For more clarification, we find the sum of the divisors of a number and find the reverse of the original number. If both the sum value and the reverse of the given number are the same then we can say that the given number is a Tcefrep number. Some examples of Tcefrep numbers are: 6, 498906, 20671542 ... etc. In this article, we will see how to check if a ...
Read MoreHow To Check Whether a Number is Strontio Number or Not in Java?
A number is said to be a Strontio number, if we multiply 2 with a four-digit number then in the resultant number the tens place and hundreds place digits are the same. In simple terms, Strontio numbers are basically four-digit numbers. When we multiply 2 with it, it results in a number whose tens place and hundred places are exactly the same. Some examples of Strontio numbers are- 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, 1001 ... etc. In this article, we will see how to check if a number is a strontio number by using Java ...
Read MoreHow To Check Whether a Number is Pointer Prime Number or Not in Java?
A number is said to be a pointer prime number, if the sum of the product value of digits and the original prime number results in the next prime number. For more clarification, we take a prime number and multiply the digits with each other and add that multiplication value with the original number. After that if we get another prime number which is next to the original prime number. Then we can say that the number is a pointer prime number. Some examples of pointer prime numbers are: 23, 61, 1123, 1231 ... etc. In this article, ...
Read MoreHow To Find the Surface Area of Hemisphere in Java?
A hemisphere refers to the exact half of a sphere. Means if we divide a sphere in two equal parts then we will get two hemispheres. Hemisphere is a three-dimensional geometrical shape which has one flat face. There are many practical examples of hemispheres. The earth divided into 2 equal parts results 2 hemispheres i.e. Northern hemisphere and Southern hemisphere. The area occupied by the outer surface of a three-dimensional object is called the surface area. Formula to calculate surface area of hemisphere − Mathematically it can be represented as $$\mathrm{Surface \:Area \:= \:2\pi\:r^2}$$ Mathematically it can be represented as ...
