The Fibonacci series is a sequence of numbers in which each number after the first two is the sum of the two preceding ones.

It is defined as follows:

F(0) = 0 F(1) = 1 F(n) = F(n-1) + F(n-2) for n > 1

So, the first few terms of the Fibonacci series are:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, …

To implement this logic in Java, we can use a loop to calculate the Fibonacci numbers one by one.

## Here is an example code and explanation:

```
public class FibonacciSeries {
public static void main(String[] args) {
int n = 10; // number of terms to generate
int first = 0, second = 1;
System.out.print("Fibonacci Series of "+n+" terms:");
for (int i = 1; i <= n; ++i) {
System.out.print(first + " ");
// compute the next term in the series
int sum = first + second;
first = second;
second = sum;
}
}
}
```

In this code, we first define the number of terms to generate as `n`

. We then initialize the first two terms of the series as `0`

and `1`

.

We use a loop to generate the next `n-2`

terms of the series. Inside the loop, we first print the current term (`first`

) and then compute the next term by adding the previous two terms (`first`

and `second`

).

Finally, we update `first`

and `second`

to prepare for the next iteration of the loop.

When we run this code, it will generate the first 10 terms of the Fibonacci series:

`Fibonacci Series of 10 terms:0 1 1 2 3 5 8 13 21 34`
