Question
How can I complete Point.java by using parts of codes in the Unused box on the left?
![PARTICIPATION
2.14.4: Implement a toString method.
АCTIVITY
Implement a toString method for the following class that returns a string containing the class name and the names and values
of all instance variables.
public class Point
{
private int x;
private int y;
}
For example,
Point origin = new Point(0, 0);
String str = origin.toString();
should set str to the string
Point[x=0,y=0]
Not all lines are useful.

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…arrow_forwardHow can you get the integer value of an enumerator?arrow_forward
