Does Java 8 provide a good way to repeat a function based on specific condition?

Question

I am having the old style while loop like below:

int i = 1, n = 5;
while(i <= n) {
    if (doSomething()) { 
        break;
    }
    i++;
}

Is it possible to do it in a good way in Java 8?

Answer 1

You can do it using IntStream and findFirst short-circuiting terminal operation. And when ever doSomething() method returns true the execution of stream pipeline will be terminated

IntStream.range(1,5)
         .filter(i -> doSomething())
         .findFirst();
