The document describes a multithreading program in Java that calculates the sum of odd and even numbers up to a user-defined maximum limit. It utilizes two threads to separately compute the sums of even and odd numbers and synchronizes access to shared variables. The main thread starts the two threads and handles user input for the maximum limit.

2. Write a multithreading program to get the maximum limit from the user to find the
sum of odd and even numbers. Create a thread to find the even numbers from 1 to the
maxlimit and get the summation. Similarly create another thread to find the odd
numbers from 1 to maxlimit and get the summation. In the main thread the summation
of both the odd sum and even sum should be calculated.

Code:
import java.util.Scanner;
class newFie {
int x =0;
int evensum = 0;
int oddsum = 0;
static int N;

public void SummationOfEven() {


synchronized (this) {
while (x < N) {
while (x % 2 == 0) {
evensum = evensum + x;
System.out.println("Even " + x);
try {
wait();
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
x++;
notify();
}
}
System.out.println("Even : " + evensum);
}
public void SummationOfOdd() {
synchronized (this) {
while (x < N) {
while (x % 2 == 1) {
oddsum = oddsum + x;
System.out.println("Odd " + x);
try {
wait();
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
x++;
notify();
}
}
System.out.println("Odd : " + oddsum);
}
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
N = sc.nextInt();
newFie obj = new newFie();
Thread t1 = new Thread(new Runnable() {
public void run() {
obj.SummationOfEven();
}
});
Thread t2 = new Thread(new Runnable() {
public void run() {
obj.SummationOfOdd();
}
});
t1.start();
t2.start();
sc.close();
}
}
