Write a java program to create 3 threads using Thread class. Three threads should calculate the sum of 1 to 5, 6 to 10 and 11to 15 respectively. After all thread finishes main thread should print the sum and average.
AIM: Write a java program
to create 3 threads using the Thread class. Three threads should calculate the sum
of 1 to 5, 6 to 10, and 11to 15 respectively. After all the thread finishes
main thread should print the sum and average.
CODE:
class MyThread1 extends Thread{
int
sum = 0;
public
void run(){
for(int
i=1;i<=5;i++){
sum+=i;
}
}
}
class MyThread2 extends Thread{
int
sum = 0;
public
void run(){
for(int
i=6;i<=10;i++){
sum+=i;
}
}
}
class MyThread3 extends Thread{
int
sum = 0;
public
void run(){
for(int
i=11;i<=15;i++){
sum+=i;
}
}
}
class threadMain3{
public
static void main(String args[]){
MyThread1
t1 = new MyThread1();
t1.start();
try{
t1.join();
}
catch(Exception
ep){
}
MyThread2
t2 = new MyThread2();
t2.start();
try{
t2.join();
}
catch(Exception
ep){
}
MyThread3
t3 = new MyThread3();
t3.start();
int
sum = 0;
sum+=t1.sum;
sum+=t2.sum;
sum+=t3.sum;
System.out.println("\nSum
of 1 to 15 is : "+sum);
float
avg = 0;
avg
= sum/15;
System.out.println("\nAverage
of 1 to 15 is : "+avg);
}
}
