Write a Program to Calculate a Series like 1/1! + 2/2! +. …. + 10/10!

class series {

public static void main(String args[]){

double sum = 0;

for(int i=1;i<=10;i++){

double fact =1, cal=0;

for(int j=1;j<=i;j++){

fact*=j;

}

cal = i/fact;

System.out.print(cal+" ");

sum = sum+cal;

}

System.out.println();

System.out.println("\nThe Sum is : "+sum+"  ");

}

}

OUTPUT :-

1.0 1.0 0.5 0.16666666666666666 0.041666666666666664 0.008333333333333333 0.001388888888888889 1.984126984126984E-4 2.48015873015873E-5 2.7557319223985893E-6

The Sum is : 2.7182815255731922

Print Table

 class printTable{

public static void main(String args[]){

int n = Integer.parseInt(args[0]);

for(int i=1;i<=10;i++){

System.out.println(n + " * " + i+" = "+i*n);

}

}

}

OUTPUT :-

javac printTable.java // For Compile

java printTable 5 // For Run

5 * 1 = 5

5 * 2 = 10

5 * 3 = 15

5 * 4 = 20

5 * 5 = 25

5 * 6 = 30

5 * 7 = 35

5 * 8 = 40

5 * 9 = 45

5 * 10 = 50
