Java program to generate the Fibonacci series:

 Here's a simple Java program to generate the Fibonacci series:


```

import java.util.Scanner;


public class FibonacciSeries {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter the number of terms: ");

        int n = scanner.nextInt();

        scanner.close();


        System.out.println("Fibonacci Series up to " + n + " terms:");

        for (int i = 0; i < n; i++) {

            System.out.print(fibonacci(i) + " ");

        }

    }


    public static int fibonacci(int n) {

        if (n <= 1) {

            return n;

        } else {

            return fibonacci(n - 1) + fibonacci(n - 2);

        }

    }

}

```


This program uses recursion to calculate each Fibonacci number. However, this approach can be inefficient for large values of `n` due to repeated calculations.


To optimize the program, you can use dynamic programming to store previously calculated Fibonacci numbers:


```

import java.util.Scanner;


public class FibonacciSeries {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter the number of terms: ");

        int n = scanner.nextInt();

        scanner.close();


        System.out.println("Fibonacci Series up to " + n + " terms:");

        int[] fib = new int[n];

        fib[0] = 0;

        fib[1] = 1;

        for (int i = 2; i < n; i++) {

            fib[i] = fib[i - 1] + fib[i - 2];

        }

        for (int i = 0; i < n; i++) {

            System.out.print(fib[i] + " ");

        }

    }

}

```


This optimized version calculates each Fibonacci number only once, resulting in improved performance for large values of `n`.
