A ten byte file would hold prime or not prime for integers. The relationship used for this compact storage of prime numbers might be described by: My 8 bits for thirty integers storage scheme could be extended to:
The "first draft" is due this Sunday, the "final draft" is due next week. I'm a complete noob in programming, but really do want to learn it. So, here's my homework 2 parts: Write a program that computes and displays the first prime numbers.
Be sure to design your program to include a function which you must write yourself called isPrime whose specification is a follows: Write program that examines the conjecture above as follows: Write a loop that sets a variable n to, 10, , 1,, 10, in turn.
For each of the specified values of n, your program should compute the sum of the logarithms of all the primes from 2 to n, and display the sum of the logs of the primes, the number n, and the ratio of these two quantities computed to 5 decimal places. The results should be displayed in a table with 6 rows for each of the 6 values of n and 3 columns the sum of the relevant logarithms, n, and the ratio.
The correct results are given later in this document. You should be able to make some changes to your solution to part 1 to solve part 2. The correct output should look like this: Sum of logs n Ratio Java program to display prime numbers with in the given range.
A number is a prime number if can be divided either by 1 or by the number itself.
Write a Program in Java to input a number and check whether it is an Automorphic Number or not. Note: An automorphic number is a number which is present in the last digit(s) of its square. Example: 25 is an automorphic number as its square is and 25 is present as the last digits. Introduction to Java Programming Choose a meaningful "Classname" that reflects the purpose of your program, and write your programming statements inside the body of the main() method.
Don't worry about the other terms and keywords now. In Java, you cannot write 1 , but need to write (x >= 1) &&. Prime Numbers Chart. Here's a chart with all the numbers from Show only primes Show only composites Show all. Enter the value of n: 15 First 15 prime numbers are: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 Program to display first prime numbers To display the first prime numbers, you can either enter n value as in the above program OR write a program like this.
If you are looking for a program that checks whether the entered number is prime or not then see: Java Program to check prime number. Program to display the prime numbers from 1 to It will display the prime numbers between 1 and
