Check which is larger 0.0 or minimum value of double and also verify this in java

Is there a way to initilize the names for students and their respective addresses? I am trying to get the Java program below to display the rollcall number with an actual name and correlating address. It would also be helpful if the names were in ascending order like the roll call numbers are. For example the programs output would look like: [rollno=1, name=Allan, address=620 pioneer st] [rollno=2, name=Chris, address=801 cheney dr] [rollno=3, name=Fedrick, address=504 plymouth ave] etc... What would that look like?  Please and thank you!   Source Code: import java.util.ArrayList;import java.util.Comparator;import java.util.Random;import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.JTextArea; class Student {    int rollno;    String name;    String address;    public Student(int roll, String name, String add)    {        super();        this.rollno = roll;        this.name = name;        this.address = add;    }    @Override    public String toString()     {…

I need help with this code in Java

Which one is greater 0.0 or double minimum value in java. Also verify your answer.

Write a program that reads integers userNum and divNum as input, and outputs userNum divided by divNum four times.Note: End with a newline. In Java, integer division discards fractions

Write a Non tail recursion and a tail recursion method in Java with a test class that does the following: The factorial of a positive integer n —which we denote as n!—is the product of n and the factorial of n 1. The factorial of 0 is 1. Write two different recursive methods in Java that each return the factorial of n. Please and Thank you

In Java (Use the isPrime Method) PrimeNumberMethod.java, provides the isPrime(int number) method for testing whether the number is prime. Use this method to find the number of prime numbers less than 10000. Below are some clarifications for the Java program   (a) The lab is to COUNT the prime numbers less than 10000.  Do NOT list the prime numbers. (b) A pair prime is two prime numbers whose difference is 2. For e.g. 3,5; 11,13; 17, 19; etc. We can use IsPrime function to count how many pair primes are there in a range from 2 to 100 for example.  Create a function pairPrime, that takes one argument. pairPrime should return the number of pair primes between 2 and the argument passed. Use the pairPrime function to count the pair primes  between 2 and 1000.  Make use of the IsPrime  function to solve this task. (This feature is worth 8 points). Use the compile/run button to test tour program. Include the output displayed. It will be similar to: command>javac…

The Java type int is an abbreviation for:

Keeping data structures and algorithms in mind, can you help me to write these two functions in java? The factorial of a positive integer n —which we denote as n!—is the product of n and the factorial of n − 1. The factorial of 0 is 1. Write two different recursive methods that each return the factorial of n. Include the two methods in a file called Test.java   What to submit: The Test.java
