Java program tutorials to print sum of nos.

 

Example: Java program to print no from 100,90,80....20

 Sam Sir

// program name Main034.java

// Java program to print no from 100,90,80....20

public class Main034

{

public static void main(String[] args)

{

int no;

for (no=100;no>=20;no=no-10)

System.out.printf("%d \n",no);

}

}

Output

100

90

80

70

60

50

40 /h3>

30

20

 

 

Example: Java program to print sum of no from 1+2+3+....10

 Sam Sir

// program name Main035.java

// Java program to print sum of no from 1+2+3+....10

public class Main035

{

public static void main(String[] args)

{

int no,s=0;

for (no=1;no<=10;no++)

s=s+no;

System.out.printf("sum of nos from 1 to 10 = %d \n",s);

}

}

Output

sum of nos from 1 to 10 = 55

 

 

Example: Javaprogram to print product of nos from 1*2*3*....10

 Sam Sir

// program name Main036.java

// Javaprogram to print product of nos from 1*2*3*....10

public class Main036

{

public static void main(String[] args)

{

int no,p=1;

for (no=1;no<=10;no++)

p=p*no;

System.out.printf("Product of nos from 1 to 10 = %d",p);

}

}

Output

Product of nos from 1 to 10 = 3628800

 


 

Example: Java program to print sum of 2 digit odd nos from 11+13+15....99

 Sam Sir

// program name Main037.java

//Java program to print sum of 2 digit odd nos from 11+13+15....99

public class Main037

{

public static void main(String[] args)

{

int no,s=0;

for (no=11;no<=99;no=no+2)

s=s+no;

System.out.printf("Sum of 2 digit odd nos from 11 to 99 = %d",s);

}

}

Output

Sum of 2 digit odd nos from 11 to 99 = 2475

 

 

 

Example: Java program to print sum of 2 digit nos divisible by 3 and 5

 Sam Sir

// program name Main038.java

// Java program to print sum of 2 digit nos divisible by 3 and 5

public class Main038

{

public static void main(String[] args)

{

int no,s=0;

for (no=10;no<=99;no++)

{

if (no%3==0 && no%5==0)

s=s+no;

}

System.out.printf("Sum of 2 digit nos divisible by 3 and 5 = %d",s);

}

}

Output

Sum of 2 digit nos divisible by 3 and 5 = 315


 

 

Example: Java program to print sum of series as 1+ 1/2+ 1/3+ 1/4 ....1/10

 Sam Sir

// program name Main039.java

// Java program to print sum of series as 1+ 1/2+ 1/3+ 1/4 ....1/10

public class Main039

{

public static void main(String[] args)

{
