simple java programs for beginners

In this post, we will develop the Factorial program in Java. We will see what are the different ways to find the factorial of a number in Java. In mathematics, the factorial of a positive integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example:- […]

In Computer Science, generally Octal number system used to store big data values. In the previous post, we had developed a Java program to convert decimal to octal value. Now in this post, we will develop a Java program to convert the octal value to decimal value. Decimal Octal 1 1 2 2 3 3

In Computer Science, generally Octal number system used to store big data values. In this post, we will develop a Java program to convert the decimal value to an octal value. Decimal Octal 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 10 9 11 10 12 In Octal

Previously we have developed a Java program to convert the temperature from Celsius to Fahrenheit. In a similar way, we can also write Java program to convert the temperature from Fahrenheit to Celsius. The formula that will be used for this problem is, ⁰C = ( 5 / 9 ) * ( ⁰F – 32

Conversion from Celsius to Fahrenheit and from Fahrenheit to Celsius has an important role in the conversion of units system. In this post, we will develop a Java program to convert Celsius to Fahrenheit. The formula used to convert from Celsius to Fahrenheit is given as, ⁰F= (⁰C * 9/5) + 32 Java Program to

Previously we have written a Java program to find the sum of digits of the given number. Now in this post, we will write a Java program to find the sum of the first and last digit of a number. Example:-Number = 12345The first digit = 1, last digit = 5Sum of first and last

We have to develop a Java program to calculate the sum of n natural numbers. Sum of natural number N as given as sum = 1+2+3+….+N Examples:-1+2+3+4+5 = 151+2+3+4+5+6+7+8+9+10 = 55 Procedure to develop a method to find the sum of N natural numbers in Java, Take the N value. Declare an iterator variable and
