Java Long and Java Short and Array elements and Fibonacci Series Java

Java long

   

  import java.util.*;

  public class JavaLong

  {

   public static void main(String[] args)

  {

   long = ;

   long timeInMilliseconds = new Date().getTime();

                System.out.println("Time in milliseconds is : " + timeInMilliseconds);           

          }

  }

Java short

                                                                                                           

public class JavaShort

{

  public static void main(String[] args)

{

short = ;

short s1 = 50;

short s2 = 42;

System.out.println("Value of short variable b1 is :" + s1);

System.out.println("Value of short variable b1 is :" + s2);

  }

}

Int to String

public class StringToIntJava

{

public static void main(String args[])

{

int i = 11;

String str = Integer.toString(i);

System.out.println("int to String : " + i);

  }

}

Calculate Average value of Array elements

public class CalculateArrayAverageExample

{

public static void main(String[] args)

{

int[] numbers = new int[]{10,20,15,25,16,60,100};

int sum = 0;

for(int i=0; i < numbers.length ; i++)

sum = sum + numbers[i];

double average = sum / numbers.length;

System.out.println("Average value of array elements is : " + average);

   }

}

Declare multiple variables in for loop

public class DeclaringMultipleVariablesInForLoop

{

public static void main(String[] args)

{

for(int i=0, j=1, k=2 ; i<5 i="" span="">

System.out.println("I : " + i + ",j : "+ j + ", k : " + k);

for(int i=0, float j; i < 5; i++);

  }

}

Fibonacci Series Java

public class JavaFibonacciSeries

{

public static void main(String[] args)

{             

int limit = 20;     

long[] series = new long[limit];

series[0] = 0;

series[1] = 1;

for(int i=2; i < limit; i++)

{

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

}

System.out.println("Fibonacci Series upto " + limit);

for(int i=0; i< limit; i++)

{

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

     }

   }
