Question

I know a bit about threads in ‘C’ but am new to them in Java. If I want to create three threads, one for addition, second for subtraction and third for multiplication I can simply do

pthread_t mathThread[3];

and while creating each thread I can assign them different functions in their arguments.

void *add(void *arg);
void *sub(void *arg);
void *mul(void *arg);

In Java, if I implement the Runnable interface there is only one run() method that I can use. How do I implement the above?

Answer 1

Create three different runnables:

Runnable[] runnables = new Runnable[] {
  new Runnable() {
    public void run() { /* add code here */ }
  },
  new Runnable() {
    public void run() { /* sub code here */ }
  },
  new Runnable() {
    public void run() { /* mul code here */ }
  },
};
