Answer 1

Answer:

sorry I only know till 18

Answer 2

Answer:

If you’re looking for a generic way to do it, a for or while loop would both work with relative ease.

with a for loop, you’d create a generic variable (e.g. “sum”), then set the loop to iterate for a variable i, initially valued at 1, until i is more than 100, adding i to sum and 1 to i each iteration.

for a while loop, you’d do the same thing, but iterate while i is less than or equal to 100.

Examples (syntax will vary)

int sum;

for (int i=1; i<=100; 1++){

sum += i;}

or

int sum;

int i=1;

while (i<=100){

sum += i; }

Explanation:

ex:

public class Sum {  

public static void main(String[] args){  

int sum=0;  

for(int i=10; i<=100; i=i+2){  

 sum = sum + i;  

}  

System.out.println(sum);  

}  

}
