Java 8 forEach with index Example

By |2019-04-02T03:15:33+05:30April 2nd, 2019|java8|

In older versions of java like before java 8, we usually iterate for loop using indexes, for example, if we want to print numbers from 0 to 10 we would generally write code like below.

for (int i = 0; i <10 ; i++) {

This example helps you to simulate the same thing using Java 8 forEach method.

Java 8 forEach with index Example:

Java 8 provides IntStream/DoubleStream interfaces to deal with indexes. The same above example can write using Java 8 or above like below.

A simple use case:

Adding all even numbers from 0 to 10.
int sum = IntStream.range(0,10)


Happy Learning 🙂
